Its integrated 12.5 mm prism and 8 mm travel helical focuser work together to locate and sharply focus guide stars without introducing the flexure common with separate guide scopes. Weighing just 18 oz (510 g), it provides a rigid, single-path solution for achieving perfectly round stars, even with long focal length instruments.\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\u003eGuiding Through a 48mm Aperture: Eliminating Opto-Mechanical Flexure\u003c\/h3\u003e\n\u003cp\u003eFor long focal length imaging, the most significant source of elongated stars is often not the mount's tracking, but differential flexure between the main telescope and a separate guide scope. The Celestron OAG solves this by using the same optical tube for both imaging and guiding. With a 48mm clear aperture, it passes the full, unvignetted light cone to your main sensor while using an internal prism to pick off a small, peripheral section of the field for your guide camera. Any deviation seen by the guider is the exact same error affecting your main image, ensuring corrections are immediate and precise.\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 12.5mm Prism Advantage: Finding Brighter Guide Stars\u003c\/h3\u003e\n\u003cp\u003eA common frustration with off-axis guiders is the difficulty of finding a sufficiently bright guide star at the edge of the field. Celestron addresses this with a large 12.5 mm prism that intercepts more light and can be adjusted radially. This allows you to position the prism closer to the better-illuminated center of the light path—just outside your main camera's sensor—dramatically increasing the brightness and availability of usable guide stars.\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\u003e8mm Helical Focuser: Precision Focus without Twisting\u003c\/h3\u003e\n\u003cp\u003eAchieving perfect, simultaneous focus for both the imaging camera and the autoguider is critical. The Celestron OAG incorporates a fixed-orientation helical focuser with 8 mm of travel, allowing you to make exceptionally fine and smooth focus adjustments to the guide camera without altering its orientation. This non-rotating mechanism prevents the guide star from drifting out of the field of view during focusing and ensures your calibration remains valid. The unit includes a complete set of adapters and spacers for SCT\/EdgeHD, M48, and M42 T-thread systems, providing a turnkey solution for most DSLR and dedicated astronomy cameras.\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\"\u003eWhy use the Celestron Off-Axis Guider instead of a separate guide scope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe primary reason is to eliminate \u003cstrong\u003edifferential flexure\u003c\/strong\u003e. A guide scope is a separate telescope with its own mounting rings and focuser, all of which can shift minutely relative to the main telescope as it tracks across the sky. The Celestron OAG uses the main telescope's optics, so any flexure or mirror shift is seen by both the imaging camera and the guide camera simultaneously, allowing the autoguider to correct for it perfectly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow do I achieve focus with both my imaging camera and the Celestron OAG?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eFirst, achieve sharp focus with your main imaging camera through the OAG.

The goal is to make the light path distance from the prism to the guide sensor equal to the distance from the OAG's center to your imaging sensor.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWill the 12.5 mm prism on the Celestron OAG vignette my full-frame camera sensor?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eNo, when properly adjusted. The prism is designed to be positioned just outside the light cone used by the main imaging sensor. The large 48mm clear aperture of the OAG body is sufficient for full-frame sensors, and you can slide the prism stalk radially outwards to ensure it does not cast a shadow on your imaging chip.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat adapters are included with the Celestron Off-Axis Guider?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Celestron OAG comes with a comprehensive set of adapters to fit most common imaging setups.

Planetary work involves taking thousands of very short exposures (video), where atmospheric turbulence is the main challenge, not mount tracking over long periods. The OAG is specifically designed for long-exposure deep-sky astrophotography of targets like the Andromeda Galaxy (M31) or the Orion Nebula (M42).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Celestron OAG with my 8\" f\/4 Newtonian telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, but it can be challenging. Fast optical systems like f\/4 Newtonians have a very limited back focus and a more pronounced coma at the edge of the field, where the OAG prism sits. While the included adapters provide flexibility, you must ensure you have enough inward focuser travel to bring the entire imaging train to focus. The large 12.5 mm prism is a significant advantage here, as it helps find brighter guide stars in the comatic outer

800\u003c\/h2\u003e\n\u003cp\u003eThe Celestron Reducer Lens .7x for the EdgeHD 800 is a custom-engineered 4-element optical accessory that transforms the telescope's native f\/10 system into a faster f\/7 instrument. This 0.7x compression factor increases the field of view by 43%, allowing you to capture expansive nebulae and galaxies within a single frame. The design provides a substantial 105mm of back focus, accommodating complex imaging trains with filter wheels, off-axis guiders, and a wide variety of dedicated astronomy cameras.\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 4-Element Design for Flat-Field Imaging\u003c\/h3\u003e\n\u003cp\u003eUnlike a generic reducer, the Celestron .7x Reducer is engineered specifically to work with the EdgeHD 800's optical system. Its 4-element design, which incorporates high-index Lanthanum glass, maintains the flat-field, coma-free performance the EdgeHD is known for, ensuring sharp stars from the center to the edge of the frame. All air-to-glass surfaces are fully multi-coated to maximize light transmission and eliminate chromatic aberration, preserving the high-contrast views of the original optical design.\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 43% Wider Field and 0.7x Faster Exposures\u003c\/h3\u003e\n\u003cp\u003eBy reducing the focal length, this accessory widens your field of view by 43%, making it possible to frame large targets like the Andromeda Galaxy (M31) or the Orion Nebula (M42) in their entirety. This focal reduction also makes the optical system one full f-stop faster, cutting required exposure times in half. You can gather the same amount of signal in a 5-minute sub-exposure as you would in a 10-minute exposure at f\/10, reducing demands on your mount's tracking and minimizing noise.\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\u003eCNC Machined Housing and 105mm Back Focus\u003c\/h3\u003e\n\u003cp\u003eThe reducer's housing is CNC machined from aluminum for precise optical alignment and spacing, critical for maintaining image quality. A key feature is the generous 105mm of optimal back focus, measured from the reducer's rear flange.

This provides a crucial intermediate step between the telescope's native f\/10 for high-resolution planetary and small galaxy imaging, and the ultra-fast f\/2 ratio available with the optional HyperStar accessory for wide-field surveys.

The camera is designed to be an excellent planetary, lunar, solar and meteor capture video camera. With a 50mm, F\/1.4 C-mount lens it will record 8th to 9th magnitude stars at 30 frames per second (33 ms exposure).  This high sensitivity with HD resolution will push video astronomy to new heights.  Sony introduced a new global shutter (GS) CMOS imaging technology called PregiusTM that redefines the global shutter imaging category and provides the best of both worlds:  fast frame rates and CCD-like imaging performance.  The technology also offers reduced dark noise, which enables higher gains without compromising image quality, as well as higher quantum efficiency.    The global shutter eliminates pixelization when imaging the moon and planets and moon caused by atmospheric agitation and high frame rates. \u003c\/p\u003e\u003cp\u003eThe unique QHYCCD design retains the 1.25-inch eyepiece design of the QHY5-II series but adds features for better cooling.  This design is more efficient in transfer of heat to the outer case enabling lower noise especially in high ambient temperatures.  The 1.25 inch design also offers the shortest possible backfocus, making the camera ideal for off-axis guiding.  In addition, the QHY5III174 uses a more robust LEMO style connector for the guide port.  These connectors are known for being both rugged and reliable.   The QHY5III174 is available in both mono and color versions. The camera is well suited for solar imaging using short focal length telescopes that will capture a full solar disk within the FOV. \u003c\/p\u003e\u003cdiv data-custom-tab\u003e\n\u003cp

full frame color sensor. The IMX410 is essentially a back-illuminated version of the sensor that used in the Nikon D750 and QHY128C cameras. In addition to BSI, the IMX410 also has larger 5.94 um pixels giving it increases sensitivity of extended objects in low light. The IMX410 is expected to be Sony's most sensitive full frame color sensor for astrophotography.\u003c\/p\u003e\u003ch2 data-animation=\"fadeInUp\"\u003eHigh Full Well Capacity and High Dynamic Range\u003c\/h2\u003e\u003cp\u003eOne benefit of the back-illuminated CMOS structure is improved full well capacity. This is particularly helpful for sensors with small pixels. When back-illumination is combined with somewhat larger pixels, the full well capacity and cynamic range are improved dramatically. The QHY410C has a full well capacity of 120k electrons! With its low read noise this produces a dynamic range greater than 17,000:1 or more than 14 STOPS. Moreover, the dynamic range remains fairly uniform even at higher gain settings.\u003c\/p\u003e\u003ch2 data-animation=\"fadeInUp\"\u003eLow Read Noise\u003c\/h2\u003e\u003cp\u003eThe QHY410C is capable of only 1.1 electron of read noise at high gain and fast readout speed. One electron of read noise means the camera can achieve a SNR\u0026gt;3 at only 3 to 4 photons. This is perfect performance when conditions are photon limited, i.e., short exposures, narrow band imaging, etc., making this large area sensor ideal for sky surveys and time domain astronomy.\u003c\/p\u003e\u003ch2 data-animation=\"fadeInUp\"\u003eBack-Illuminated\u003c\/h2\u003e\u003cp\u003eSony's Exmor R back-illuminated technology produces sensors that Sony estimates are twice as sensitive as similar front illuminated sensors. QHYCCD tests have borne out this claim. Additionally, Sony sensors are well known for their low dark current. QHYCCD's proprietary thermal noise reduction technology and the QHY40C's dual-stage regulated thermoelectric cooling further reduce dark current to extremely low levels for clean, long duration exposures when required.\u003c\/p\u003e\u003cdiv data-custom-tab\u003e\n\u003cp data-custom-tab-title\u003eSpecifications\u003c\/p\u003e\n\u003cdiv\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eQHY410C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003eSensor\u003c\/td\u003e\n\u003ctd width=\"116\"\u003eSONY IMX410 Full Frame BSI CMOS Sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"116\"\u003eAR Coating On CMOS chamber\u003c\/td\u003e\n\u003ctd width=\"116\"\u003eYes.

the sensor supplier.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThis sensor is specially designed and manufactured with amateur astronomers in mind who wanted a mono sensor

is 27mm x 21.6mm. Compared to the QHY8L APS-C format of 23.4 x 15.8, the APS-H sensor is significantly larger with over 50% larger image area.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe reason for desiring an APS-H size mono sensor is that there are no other existing mono sensors in size between the KAF-8300 (4\/3inch) and the KAI-11002 (35mm format).\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThis sensor has 16 Megapixels and the APS-H format is suitable for most telescopes, including SCT's that cannot fully illuminate a 35mm frame without some vignetting or distortion at the edges.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eIt is also suitable for commonly available 2inch filters.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe pixel size of this sensor is 6.0um x 6.0um, slightly bigger than the KAF-8300's 5.4um but, due to the larger size of the sensor, it has nearly twice as many pixels as the 8300.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe QE is similar to or higher than 8300 and the 37ke- full well capacity is almost 50% greater than the 8300's 25.5ke-.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eSince the read noise is comparable to the 8300, the dynamic range can be calculated at about 1.5X greater than the 8300.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThis sensor also comes in a color version on request.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\"A\" Series Camera - Fully Integrated:\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003e\u003c\/strong\u003eThe QHY16200A belongs to the new QHYCCD \"A\" series camera family. \"A\" stands for \"ALL-IN-ONE\".\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe camera includes a built-in motor driven filter wheel and natively supports the QHYOAG.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe OAG can be installed on the camera solidly with six screws, consuming a minimum of back focus, precious for some optical systems.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe filter wheels available for the QHY16200A accept 2\" mounted filters, or 50mm unmounted round filters, in carousels with 5 or 7 positions.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe camera is compatible with the medium size QHYOAG.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eIn addition to the filter wheel and OAG, this \"A\" series camera offers an internal USB HUB (2.0) that provides two USB host port and a USB to dual RS232 converter.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eA guiding camera, mount and electric focuser can be connected directly to the camera instead of the computer to reduce cable clutter and the chance of signal loss due to the long cables.

It acts as a temporary high-speed storage space on the camera itself. When you take an image, the data is read from the sensor and immediately stored in this buffer before being sent to the computer. This prevents data loss if your computer's USB bus is momentarily busy or experiences a slight delay, ensuring that no frames are dropped during a long or high-speed imaging sequence.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the QHY6060 for asteroid or supernova surveys?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eAbsolutely. The QHY6060 is exceptionally well-suited for survey work. Its combination of a very large field of view, high resolution, and excellent sensitivity allows you to cover vast areas of the sky efficiently. A robotic telescope equipped with this camera could repeatedly image large patches of the sky, enabling automated software to perform blink comparison to discover new asteroids or transient events like supernovae.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eImage Sensor\u003c\/td\u003e\n\u003ctd\u003eGpixel GSENSE6060\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003eMonochrome\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor Architecture\u003c\/td\u003e\n\u003ctd\u003eFront-Side Illuminated (FSI) and Back-Side Illuminated (BSI) versions available\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePixel Size\u003c\/td\u003e\n\u003ctd\u003e10µm x 10µm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEffective Pixels\u003c\/td\u003e\n\u003ctd\u003e37.6 Megapixels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEffective Image Area\u003c\/td\u003e\n\u003ctd\u003e61.34mm x 61.34mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e6134 x 6134 pixels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eA\/D Conversion\u003c\/td\u003e\n\u003ctd\u003e14-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFull Well Capacity\u003c\/td\u003e\n\u003ctd\u003eFSI: 70ke- | BSI: TBD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRead Noise\u003c\/td\u003e\n\u003ctd\u003e4.7e- (High Gain Channel)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDark Current\u003c\/td\u003e\n\u003ctd\u003eFSI: 0.2e-\/pixel\/sec @ -15℃ | BSI: TBD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExposure Time Range\u003c\/td\u003e\n\u003ctd\u003e20µs -
