This f\/15 system is engineered for high-magnification views of the solar system, resolving details with 0.52 arc-second Dawes limit resolution, while the NexStar+ controller puts over 40,000 celestial objects at your command. With 661x the light gathering power of the human eye, this telescope delivers exceptionally detailed and sharp images of the Moon's craters and Jupiter's atmospheric bands directly from a city backyard.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e180mm f\/15 Maksutov Optics: High-Contrast Planetary and Lunar Views\u003c\/h3\u003e\n\u003cp\u003eThe Maksutov-Cassegrain design is specialized for delivering sharp, high-contrast images, making it ideal for planetary and lunar observation. Its long 2700mm focal length and f\/15 ratio provide high magnification with standard eyepieces, achieving 96x with the included 28mm 2\" eyepiece. The optical system's central obstruction is just 23.3% by diameter, significantly smaller than typical Schmidt-Cassegrains, which minimizes diffraction and boosts contrast for discerning fine details on bright objects.\u003c\/p\u003e\n\u003cp\u003eUnlike Schmidt-Cassegrains, the secondary mirror is a reflective spot on the inside of the corrector lens, an integrated design that rarely requires collimation. The primary trade-off for this optical precision is a longer thermal acclimation time due to the thick corrector plate.

The long 2700mm focal length and high-contrast optics are ideal for resolving fine details. With the included 28mm eyepiece (96x), you will easily see the primary cloud bands and the four Galilean moons. Adding a higher-power eyepiece or a Barlow lens to push magnification towards 200x will reveal intricate details like the Great Red Spot, smaller ovals, and festoons within the cloud bands, especially on nights of steady seeing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Celestron AVX 700 Mak for deep-sky imaging of a target like the Orion Nebula (M42)?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, but with considerations. The f\/15 focal ratio is very slow, requiring much longer sub-exposure times compared to faster telescopes, which makes guiding more critical. The 2700mm focal length is also very high, making it better suited for smaller deep-sky objects like planetary nebulae (M57, the Ring Nebula) and globular clusters (M13, the Hercules Cluster) rather than large targets like the Orion Nebula (M42). While possible, a focal reducer would be highly recommended to make deep-sky imaging more manageable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the advantage of the f\/15 focal ratio on the AVX 700 Mak?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe primary advantage of the slow f\/15 focal ratio is in high-magnification planetary and lunar viewing. It allows you to achieve high powers using eyepieces with longer focal lengths, which typically have better eye relief and are more comfortable to look through. It also makes the telescope very tolerant of less-expensive eyepiece designs, delivering sharp views across the field without requiring complex, premium eyepieces.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eDoes the Advanced VX mount have enough capacity for the 19 lb optical tube and a camera?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes.

This heavy piece of glass has more thermal mass than the thinner corrector plate on a Schmidt-Cassegrain of similar aperture. As a result, it takes longer for the optics to reach thermal equilibrium with the ambient night air. For best performance, it's recommended to set the telescope outside for at least an hour before observing.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat does the dual saddle plate on the Advanced VX mount let me do?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe dual saddle plate adds significant versatility to your setup.

entirely by your smartphone. Its f\/13 optical system is engineered for high-contrast views of the Moon and planets, delivering 53x and 132x magnification with the two included eyepieces. With its integrated WiFi and Celestron's SkyPortal app, you can align the telescope and automatically slew to thousands of objects without a traditional hand controller.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e102mm Maksutov-Cassegrain Optics: High-Contrast Planetary Views at f\/13\u003c\/h3\u003e\n\u003cp\u003eThe Maksutov-Cassegrain (MAK) design uses both a mirror and a corrector lens to produce sharp, high-contrast images that are virtually free of chromatic aberration. The Astro Fi 102mm's long f\/13 focal ratio excels at resolving fine details, from craters on the Moon to the rings of Saturn and Jupiter's cloud bands. A key benefit of the MAK design is its stability; the secondary mirror is a reflective spot on the inside of the corrector, eliminating the need for periodic collimation.\u003c\/p\u003e\n\u003cp\u003eThis design's secondary obstruction is just 34% by diameter, smaller than many other catadioptric designs, which enhances contrast for planetary observation. The only trade-off for this optical precision is a longer thermal acclimation time, as the thick corrector plate needs time to adjust to the ambient nighttime temperature for the sharpest possible views.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eIntegrated WiFi Control: GoTo Alignment with Your Smartphone\u003c\/h3\u003e\n\u003cp\u003eThe Astro Fi mount creates its own WiFi network, allowing you to connect and control the telescope directly from your smartphone or tablet using the Celestron SkyPortal app. This completely wireless experience replaces a traditional hand controller. Simply point your device at the sky, tap on an object you want to see, and the Astro Fi 102mm automatically slews to it.\u003c\/p\u003e\n\u003cp\u003eAlignment is handled by Celestron's proven SkyAlign technology. You don't need to know the names of the stars; just center any three bright objects in the eyepiece, and the app calculates the telescope's position. From there, you can take a guided Sky Tour of the best objects currently visible based on your specific time and location.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Complete 16 lb Grab-and-Go System\u003c\/h3\u003e\n\u003cp\u003eWeighing a total of just 16 lbs, the Astro Fi 102mm is built for portability. The entire system—optical tube, mount, and tripod—assembles in minutes without tools, making it ideal for impromptu backyard sessions or travel to dark-sky sites.

Telescope\u003c\/h2\u003e\n\u003cp\u003eThe Celestron CGEM II 7\" Maksutov-Cassegrain Telescope pairs a 180mm (7.08\") aperture with a long 2700mm focal length (f\/15) to deliver high-contrast planetary and lunar views. Its StarBright XLT coatings and minimal 5% secondary obstruction by area ensure maximum light transmission, resolving details down to 0.52 arc seconds (Dawes limit). The robust CGEM II equatorial mount supports a 40 lbs instrument load on 2\" steel tripod legs, easily handling the 19 lbs optical tube and providing a stable platform for the 40,000+ object NexStar+ database.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA 180mm f\/15 System for High-Contrast Planetary Views\u003c\/h3\u003e\n\u003cp\u003eThe Maksutov-Cassegrain design is engineered for superior contrast, making it a specialized instrument for detailed solar system and small deep-sky observation. The long f\/15 focal ratio darkens the sky background and provides high magnification for resolving features like Jupiter's cloud bands, Saturn's rings, and fine lunar craters. Its optical system produces bright, sharp images that are virtually free of chromatic aberration.\u003c\/p\u003e\n\u003cp\u003eA key advantage of the Mak design is its \"secondary spot,\" a reflective coating applied directly to the corrector lens. This results in a tiny central obstruction of just 5% by area, significantly less than a comparable Schmidt-Cassegrain, which is the source of its signature high-contrast views. This design also means the telescope does not require periodic collimation. The primary trade-off is that the thick 180mm corrector plate requires a longer cool-down time to acclimate to ambient temperatures.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCGEM II Mount: 40 lb Payload Capacity and Meridian-Crossing Stability\u003c\/h3\u003e\n\u003cp\u003eThe CGEM II mount provides the rigid, vibration-free foundation necessary for high-magnification viewing and imaging. Its 40 lbs instrument load capacity easily supports the 19 lbs optical tube, leaving over 20 lbs of capacity for cameras, guide scopes, and other accessories. The tripod features 2\" diameter steel legs with graduated markings for easy, repeatable setup.\u003c\/p\u003e\n\u003cp\u003eDesigned for astrophotography, the mount incorporates low cog DC servo motors with integrated optical encoders for smooth, accurate tracking. For imagers, the CGEM II can track an object up to 20° past the meridian before a meridian flip is required, allowing you to capture data during the best part of the night. All motor and accessory cabling is housed internally, preventing snags and simplifying setup and breakdown.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eGoTo \u0026amp; Tracking: All-Star Alignment and Permanent Periodic Error Correction\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the system is the NexStar+ hand controller, giving you access to a database of over 40,000 celestial objects. The mount's GoTo system is complemented by Celestron's innovative All-Star Polar Alignment procedure, which allows for a quick and accurate alignment using any bright star, even if Polaris is not visible. This process typically takes only 15 minutes.\u003c\/p\u003e\n\u003cp\u003eFor long-exposure imaging, tracking accuracy is critical. The CGEM II features Permanent Periodic Error Correction (PPEC), which allows you to record and correct for the inherent periodic errors in the worm gears. Once recorded, the correction is stored in the mount's memory. For the most demanding applications, a dedicated autoguide port allows the connection of an autoguiding camera to achieve sub-arcsecond tracking precision.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCGEM II 700 Mak vs. 8\" SCT: The High-Contrast Specialist\u003c\/h3\u003e\n\u003cp\u003eWhen choosing between this 7\" Maksutov and a more conventional 8\" Schmidt-Cassegrain (SCT) on the same mount, the decision comes down to your primary targets.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe 8\" SCT's Advantage:\u003c\/strong\u003e An 8\" SCT gathers more light and typically operates at a faster f\/10 focal ratio.

Telescope\u003c\/h2\u003e\n\u003cp\u003eThe Celestron CGX 7\" Maksutov Cassegrain Telescope combines a 180mm high-contrast optical system with the robust, imaging-focused CGX equatorial mount. With its long 2700mm focal length and f\/15 ratio, this instrument is engineered for detailed views of planets, the lunar surface, and compact deep-sky objects. The CGX mount provides an exceptionally stable platform with its 55 lb instrument capacity, easily handling the 19 lb optical tube and a full imaging payload. This package resolves details down to a 0.52 arc second Dawes limit, with its StarBright XLT coated optics gathering 661 times more light than the human eye. The included NexStar+ controller puts a database of over 40,000 celestial objects at your fingertips, all driven by high-precision DC servo motors.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e180mm f\/15 Maksutov-Cassegrain Optics: High-Contrast Planetary Views\u003c\/h3\u003e\n\u003cp\u003eThe Maksutov-Cassegrain design is purpose-built for high-magnification, high-contrast observing. This 180mm optical tube features a minimal secondary mirror obstruction of just 22% by diameter, significantly less than comparable Schmidt-Cassegrain designs. This results in sharper, higher-contrast images that reveal subtle details in Jupiter's cloud bands, Saturn's rings, and fine lunar craters.\u003c\/p\u003e\n\u003cp\u003eThe Mak design uses a spherical secondary mirror spot coated on the inside of the corrector lens, which eliminates the need for periodic secondary collimation. While the thick corrector plate requires more time to acclimate to ambient temperatures, the reward is exceptionally sharp and color-pure views, making it a powerful tool for urban astronomers or anyone prioritizing planetary and double-star observation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eCGX Mount: A 55 lb Capacity Imaging Foundation\u003c\/h3\u003e\n\u003cp\u003eThe CGX mount is engineered for stability, providing a vibration-free foundation for serious imaging. Its 55 lb load capacity offers a massive performance margin for the 19 lb optical tube, ensuring rigidity even when loaded with a guide scope, camera, and other accessories. The heavy-duty tripod, with its 2\" diameter steel legs and wide stance, eliminates flexure and dampens vibrations quickly.\u003c\/p\u003e\n\u003cp\u003eDesigned for portability, the entire system breaks down into manageable components without tools. The mount head weighs 44 lbs, the tripod 19.2 lbs, and the two 11 lb counterweights are easily handled. Ergonomic carry handles and a tripod accessory tray that nests into the collapsed legs make transport and setup efficient, even for a single person.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDC Servos and PPEC: Sub-Arcsecond Tracking for Long Exposures\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the CGX are low-cog DC servo motors with integrated optical encoders, delivering smooth, precise tracking essential for long-exposure astrophotography. A belt-and-pulley system connects the motors to the worm gears, minimizing the gear backlash common in lesser mounts. This ensures your guide camera makes fewer, smaller corrections.\u003c\/p\u003e\n\u003cp\u003eCelestron’s All-Star Polar Alignment routine allows for a quick and accurate setup without a polar scope, even if you can't see Polaris. Once aligned, you can train the mount's Permanent Periodic Error Correction (PPEC) to remove inherent tracking errors from the worm gear, resulting in rounder stars and sharper images. For ultimate precision, a dedicated autoguide port is standard.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eImaging Intelligence: Meridian Freedom and Remote Safety: Designed for Unattended Imaging\u003c\/h3\u003e\n\u003cp\u003eThe CGX is built for modern, computer-controlled astrophotography. The mount can track an object up to 20° past the meridian before needing to perform a meridian flip, allowing you to capture data on your target during its optimal position in the sky. Built-in optical switches on each axis automatically stop the motors if a physical strike is imminent, protecting your equipment during remote or unattended sessions.\u003c\/p\u003e\n\u003cp\u003eWith a USB port on both the mount and hand control, plus two auxiliary ports, the CGX is fully controllable via a PC.

celestial objects at your command. Its long 1500mm focal length and f\/12 focal ratio are engineered for high-magnification views of the planets, delivering up to 167x with the included 9mm eyepiece. With 329x the light-gathering power of the human eye and a resolving power of 0.91 arc seconds, this system reveals fine details on Jupiter's cloud bands and the rings of Saturn.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHigh-Contrast 127mm Maksutov-Cassegrain Optics\u003c\/h3\u003e\n\u003cp\u003eThe Maksutov-Cassegrain (MAK) design is renowned for producing sharp, high-contrast images, making it ideal for planetary and lunar observation. The 127mm aperture gathers 329x more light than the naked eye, resolving details down to a stellar magnitude of 13. The long f\/12 focal ratio darkens the sky background and provides the high magnification needed to resolve planetary features, double stars, and the cores of bright globular clusters.\u003c\/p\u003e\n\u003cp\u003eUnlike other catadioptric designs, the MAK's secondary mirror is a reflective spot on the inside of the corrector lens. This eliminates the need for user collimation and, because the spot is smaller than a physical secondary mirror, it increases image contrast. This makes the 127SLT an excellent choice for observing subtle details like Mars' polar caps or the Cassini Division in Saturn's rings right out of the box.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eNexStar+ GoTo System: 40,000 Objects at Your Fingertips\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the 127SLT is the NexStar+ computerized hand control. This system gives you access to a database of over 40,000 objects, including planets, nebulae, galaxies, and star clusters. Once aligned, simply select an object from the menu, and the mount's DC servo motors will automatically point the telescope, tracking it as it moves across the sky at a sidereal, solar, or lunar rate.\u003c\/p\u003e\n\u003cp\u003eFor those new to the night sky, the built-in Sky Tour feature is your personal guide to the cosmos. It automatically generates a list of the best objects visible for your specific time and location.

Simply center any three bright objects in the eyepiece, and the NexStar+ system triangulates its position. You don't need to know the names of the stars; you can even use the Moon or bright planets. This no-tool, intuitive process means you can go from setup to observing in just a few minutes.\u003c\/p\u003e\n\u003cp\u003eThe entire system is supported by a sturdy, pre-assembled stainless steel tripod with 1.25\" diameter legs.

The package includes two 1.25\" eyepieces: a 25mm for wide-field scanning at 60x magnification and a 9mm for high-power views at 167x. A StarPointer red dot finderscope makes it easy to aim the telescope, and a 1.25\" star diagonal provides a comfortable viewing angle.\u003c\/p\u003e\n\u003cp\u003eDesigned for portability, the entire system can be powered by 8 AA batteries (not included), freeing you from cords and allowing you to travel to remote dark-sky sites.

Telescope\u003c\/h2\u003e\n\u003cp\u003eThe Celestron NexStar 90SLT Computerized Telescope combines a 90mm Maksutov-Cassegrain optical system with a fully computerized GoTo mount, putting a 40,000-object database at your command. Its long 1250mm focal length (f\/14) is ideal for high-magnification views of the Moon and planets, delivering magnifications of 50x and 139x with the two included eyepieces. This optical system gathers 165x more light than the human eye and achieves a limiting stellar magnitude of 12.3, resolving details down to 1.29 arc seconds.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eHigh-Contrast Views from a 90mm Maksutov-Cassegrain\u003c\/h3\u003e\n\u003cp\u003eThe Maksutov-Cassegrain (MAK) design is renowned for producing sharp, high-contrast images, making it perfect for planetary detail. Unlike other designs, the 90SLT's secondary mirror is a reflective spot on the inside of the corrector lens, a design that eliminates the need for periodic collimation and boosts contrast. This catadioptric system delivers views that are virtually free of chromatic aberration, revealing crisp details on Jupiter's cloud bands and Saturn's rings. The primary trade-off for this optical purity is that the heavy corrector plate requires more time to acclimate to nighttime temperatures compared to other designs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eNexStar+ GoTo System: 40,000 Objects at Your Fingertips\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the 90SLT is the NexStar+ computerized hand control. This system gives you automated access to a database of 40,000 celestial objects, including galaxies, star clusters, and nebulae. Simply select an object from the menu, and the telescope's motorized altazimuth mount will slew to it automatically. For those unsure of what to see, the Sky Tour feature generates a custom list of the best objects visible for your specific time and location. With nine different slew speeds, you can move rapidly across the sky or make fine adjustments to perfectly center your target.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eSkyAlign Technology: A 3-Object Alignment in Minutes\u003c\/h3\u003e\n\u003cp\u003eCelestron's proprietary SkyAlign procedure makes setup incredibly simple, even for absolute beginners. Just point the telescope at any three bright celestial objects—you don't even need to know their names—and the onboard computer will triangulate its position. In minutes, your telescope is aligned and ready to locate any target in its 40,000-object database. For users who prefer traditional methods, the system also supports 2-Star, 1-Star, and Solar System alignment procedures.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eGrab-and-Go Astronomy: No-Tool Setup and 8 AA Battery Power\u003c\/h3\u003e\n\u003cp\u003eThe entire NexStar 90SLT system is designed for portability and quick deployment. The mount and optical tube attach to the pre-assembled steel tripod with a quick-release mechanism, requiring no tools for setup.

The true advantage of the NexStar 90SLT is its computerized brain. Instead of spending hours learning to star-hop with charts, the 90SLT's 40,000-object database allows you to immediately observe hundreds of galaxies, clusters, and double stars that would be nearly impossible for a novice to find manually. It transforms the telescope from a simple magnifier into a guided tour of the cosmos.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat can I see with the Celestron NexStar 90SLT?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe NexStar 90SLT excels at high-magnification solar system viewing. You can expect to see detailed craters on the Moon, the phases of Venus, Mars' polar caps, Jupiter's four largest moons and cloud bands, and the rings of Saturn. Its 90mm aperture also gathers enough light to show brighter deep-sky objects like the Orion Nebula (M42) and the Hercules Cluster (M13) from a dark-sky site.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the NexStar 90SLT perform on Jupiter and Saturn?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThis is where the Maksutov-Cassegrain optics shine.

A comparable 6-inch SCT often has a larger secondary obstruction, which slightly reduces contrast. The Maksutov's optical design inherently produces sharper, higher-contrast views, making it a specialist for resolving fine detail on bright objects. However, the trade-off is a slower f\/12 focal ratio, which means the Skymax is less suited for wide-field, deep-sky astrophotography compared to a faster f\/10 SCT.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow does the Sky-Watcher Skymax 150 perform on Jupiter with its 1800mm focal length?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Skymax 150's 1800mm focal length makes it an exceptional instrument for observing Jupiter.

You can expect to clearly see the primary equatorial belts, distinguish color variations, and spot the Great Red Spot when it is visible.

Its 151mm aperture gathers enough light to resolve the dense cores of bright clusters like the Hercules Cluster (M13) into individual stars.

Its f\/15 focal ratio and minimal 5% central obstruction by area produce exceptionally high-contrast images, resolving details down to the 0.64 arcsecond Dawes limit. The optical system uses Radiant Aluminum Quartz (RAQ) mirror coatings to achieve 94% reflectivity, ensuring bright images even at the 354x maximum magnification.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e2700mm Focal Length in a 22\" Tube\u003c\/h3\u003e\n\u003cp\u003eThe Maksutov-Cassegrain design concentrates a powerful 2700mm focal length into a compact optical tube that is just 22 inches long and weighs only 19 pounds.

This minimizes diffraction effects compared to other catadioptric designs, resulting in sharper, higher-contrast images.

Telescope is engineered for high-magnification planetary and lunar observation, featuring a native f\/11.8 focal ratio and secondary mirror with 99% reflectivity dielectric coatings for maximum image brightness. With the included 0.65x focal reducer, the system converts to a faster f\/7.68 for wider deep-sky views, offering two distinct optical configurations in one package. The optical tube's light gathering power is 254X that of the naked eye, and it connects to a universe of accessories via its standard SCT male thread (2\" 24TPI).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eRumak-Maksutov Optics: 99% Reflectivity for High-Contrast Views\u003c\/h3\u003e\n\u003cp\u003eThe MK127 uses a Rumak-style Maksutov-Cassegrain design, which features a separated secondary mirror. This improves optical alignment and correction, delivering sharper stellar images and higher contrast on planetary details compared to standard Maksutovs. The primary mirror has a multi-coated aluminum finish, while the secondary boasts 99% reflectivity dielectric coatings to maximize light transmission to your eyepiece.\u003c\/p\u003e\n\u003cp\u003eUnlike achromatic refractors, this catadioptric system is free of chromatic aberration. Bright targets like Jupiter, the lunar limb, and bright stars are rendered without distracting purple fringing, revealing crisp, natural detail. While the enclosed tube requires time to acclimate to ambient temperature, the reward is apochromatic-level views from a remarkably compact instrument.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDual Focal Ratios: From f\/11.8 to f\/7.68 with the 0.65x Reducer\u003c\/h3\u003e\n\u003cp\u003eThis telescope includes a 0.65x focal reducer, transforming its optical characteristics with a simple accessory change. At its native f\/11.8, the long focal length is ideal for achieving high power on small targets, allowing you to resolve cloud bands on Jupiter, the Cassini Division in Saturn's rings, and tiny craterlets on the Moon.\u003c\/p\u003e\n\u003cp\u003eAttaching the reducer converts the scope to a faster f\/7.68 system. This shortens exposure times for astrophotography and provides a wider true field of view for observing larger deep-sky objects like the Orion Nebula (M42) or the Andromeda Galaxy (M31).

It attaches to any mount accepting a Vixen-style rail with its included 210mm dovetail plate, providing a secure connection for visual use or imaging. The internal dual-speed focuser allows for smooth and precise adjustments, which is critical for achieving perfect sharpness at high magnification.\u003c\/p\u003e\n\u003cp\u003eThe coarse knob allows you to find initial focus quickly, while the fine-adjustment knob gives you the delicate control needed to snap planetary details into sharp relief.

planetary-friendly f\/13 focal ratio. Weighing only 4.83 lbs, this optical tube assembly delivers the high-magnification views of a much larger refractor in a package built for travel. With a theoretical resolution of 1.1 arc seconds and 210x light gathering power over the naked eye, the MK105 is engineered specifically for detailed observation of the Moon and planets.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eMaksutov-Cassegrain Optics: A 1365mm Focal Length for High-Power Views\u003c\/h3\u003e\n\u003cp\u003eThe MK105's design prioritizes high-magnification clarity. Its 1365mm focal length and slow f\/13 focal ratio are ideal for pushing magnification on bright targets like Jupiter's cloud bands, Saturn's rings, and lunar craters.

This compact form factor is a direct benefit of the folded light path of the Maksutov-Cassegrain design, achieving a long focal length in a tube less than half the size of an equivalent refractor. The internal focusing mechanism further reduces its footprint by eliminating the need for an external drawtube.\u003c\/p\u003e\n\u003cp\u003eThe metal optical tube ensures the internal components remain collimated during transport, making it a reliable choice for trips to dark-sky sites or for quick backyard sessions.

Maksutov-Cassegrain optical system into a highly portable package for detailed lunar, planetary, and terrestrial viewing. It connects to standard astronomical mounts using the included 70mm Vixen-style dovetail plate and is compatible with all 1.25-inch eyepieces and accessories.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe 90mm Maksutov-Cassegrain Optical System\u003c\/h3\u003e\n\u003cp\u003eThe MK90's two-element Maksutov-Cassegrain optics deliver the sharp, high-contrast images this design is known for. The 90mm aperture gathers enough light for definitive views of the Moon's craters, Jupiter's cloud belts, and the rings of Saturn. This long focal length design excels at high magnification, making it an ideal instrument for planetary observers who need crisp detail.\u003c\/p\u003e\n\u003cp\u003eWhile perfect for celestial targets, the Maksutov design also produces a correctly oriented image (with an optional diagonal), making the MK90 a powerful spotting scope for daytime bird watching and nature observation. The trade-off for its high-power planetary resolution is a narrower field of view compared to a short-tube refractor, making it less suited for sweeping across the widest sections of the Milky Way.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eAdvanced Internal Baffling for High-Contrast Views\u003c\/h3\u003e\n\u003cp\u003eSvbony has engineered the MK90 with a tapered internal baffle tube specifically designed to intercept and absorb stray light. This feature is critical for maintaining image contrast, especially when observing bright objects like the Moon or planets against the blackness of space. By preventing off-axis light from reaching the focal plane, the background sky remains darker and subtle surface details are more easily visible.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eA Versatile 70mm Vixen Dovetail \u0026amp; Tripod Mount\u003c\/h3\u003e\n\u003cp\u003eThe MK90 optical tube is built for versatility in the field. It includes a 70mm Vixen-style dovetail plate, the de-facto standard for most modern astronomical alt-azimuth and equatorial mounts. For more casual or terrestrial use, the mounting base also includes a standard UNC ¼-20 threaded hole, allowing you to attach the telescope directly to a sturdy photographic tripod without any additional hardware.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat kind of mount do I need for the Svbony MK90 telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Svbony MK90 is very flexible.

The Maksutov-Cassegrain design provides high magnification and sharp images.

Carbon fibre has a very low coefficient of thermal expansion, meaning it doesn't shrink or expand significantly as the ambient temperature changes throughout the night. At a long focal length of 4000mm, even a tiny change in tube length can shift the focal point. The carbon fibre tube ensures the focus you set at the beginning of the night remains sharp for hours, a crucial feature for long imaging sessions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the OMC200 De-Luxe for deep-sky imaging?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eWhile possible, it is not its primary design function.
