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 \u003ca href=\"\/en-int\/collections\/guide-cameras\"\u003eguide camera\u003c\/a\u003e.

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 \u003ca href=\"\/en-int\/collections\/cameras\"\u003eastronomy cameras\u003c\/a\u003e.\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. Then, without changing the telescope's focus, adjust the OAG's \u003cstrong\u003e8 mm helical focuser\u003c\/strong\u003e until the stars in your guide camera are also sharp. 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.

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.

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 ample room for accessories like off-axis guiders, filter wheels, and adaptive optics systems without compromising the flat-field correction, a significant advantage over reducers with shorter back focus requirements.\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 f\/7 Midpoint for the EdgeHD 800\u003c\/h3\u003e\n\u003cp\u003eThe .7x Reducer gives your EdgeHD 800 a versatile f\/7 focal ratio, creating a three-in-one imaging platform. 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 has a custom ST-4 guide port.

1920x1080 resolution. It achieves a maximum frame rate of 135 FPS over its USB 3.0 interface, and its Super High Conversion Gain (sHCG) gives read noise as low as 0.5e- in high gain mode. The 12-bit ADC and 12ke- full well complete the sensor figures.\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\u003eIMX462 STARVIS Sensor: 2.1 MP Resolution with 2.9µm Pixels\u003c\/h3\u003e\n\u003cp\u003eAt the core of the QHY5III462C is the Sony IMX462 STARVIS sensor, a back-illuminated chip featuring a 1920x1080 pixel array and a 2.9µm pixel size. It has the same pixel size and resolution as the sensor in the QHY5III290, which some of the best planetary imagers in the world used. The 1\/2.8 inch sensor has a 6.39mm diagonal.\u003c\/p\u003e\n\u003cp\u003eIt is the sixth-generation Sony STARVIS sensor, and back illumination doubled visible sensitivity over front-illuminated 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\u003esHCG Mode: Achieving 0.5e- Read Noise\u003c\/h3\u003e\n\u003cp\u003eThe IMX462 sensor incorporates Super High Conversion Gain (sHCG) technology, which uses a lower capacitance so a small charge converts to a high voltage, giving higher sensitivity in low light. Read noise is as low as 0.5 electrons in high gain mode.\u003c\/p\u003e\n\u003cp\u003eThis is ideal for stacking hundreds or thousands of short planetary images.

The photodiode part of the pixel well is physically deeper than in previous Sony BSI sensors, so longer wavelengths penetrate deeper into the substrate. The peak QE in the NIR around 800nm is as high as the peak QE in visible wavelengths.\u003c\/p\u003e\n\u003cp\u003eThe organic dye RGB filters over the pixels become completely transparent in the NIR, so good RGB colour balance needs an external UV\/IR filter that blocks NIR. Using the included IR850nm filter, which passes light above 850nm, you can isolate this spectral region. For methane band imaging, the high NIR QE is welcome news for imagers using a methane filter around 880nm (not included).\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\u003e135 FPS at 8-bit over USB 3.0\u003c\/h3\u003e\n\u003cp\u003eThe QHY5III462C streams full-resolution 1920x1080 frames at up to 135 FPS in 8-bit mode. The camera connects through a USB 3.0 Type-B interface, which also powers it. Not every computer reaches the maximum frame rate (an i7 quad-core is generally fine); closing other programs, setting a 1 ms exposure and lowering USB Traffic help raise it. The QHY5III462C has no built-in image buffer, so frames can be lost during transmission.\u003c\/p\u003e\n\u003cp\u003eThe camera's analog-to-digital converter (ADC) operates at 12-bit precision, capturing over 4,000 levels of brightness.

planetary and deep-sky targets. Its sensor is a 1-inch back-illuminated chip with a full well capacity of 15,500 e-. A dual-stage TEC cooler chills the sensor to -40°C below ambient, with a dark current of 0.0024 e-\/pixel\/sec at -15°C; read noise is as low as 1.0e- at high gain. A 128MB DDR2 image buffer ensures stable data transfer over USB 3.0, sustaining up to 19 FPS at full resolution in 8-bit mode.\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\u003e20 MP Sony IMX183 BSI Sensor: High Resolution with 2.4μm Pixels\u003c\/h3\u003e\n\u003cp\u003eAt the core of the QHY183C is Sony's 1-inch format IMX183 sensor, which delivers a resolution of 5544 x 3684 across a 15.99mm diagonal. The small 2.4μm pixels give fine sampling at short and moderate focal lengths, and the QHY183 suits both planetary and deep-sky imaging.\u003c\/p\u003e\n\u003cp\u003eThe sensor's back-illuminated (BSI) structure improves quantum efficiency by moving the metal wiring layer behind the photodiodes.

At its lowest gain setting, it provides a read noise of 2.7e- and gives you access to the full 15,500 e- well capacity, . As you increase the gain, the read noise drops to 1.0e-.\u003c\/p\u003e\n\u003cp\u003eThe camera reaches unity gain at a gain setting of 10.

This 12-bit depth provides 4,096 levels of signal, ensuring smooth transitions in your images.\u003c\/p\u003e\n\u003cp\u003eThe QHY183C has anti-glow control, which reduces amplifier glow in long exposures; remaining glow is removed with dark frames.\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\u003e-40°C Cooling System with Integrated Anti-Dew Heater\u003c\/h3\u003e\n\u003cp\u003eEffective thermal management is crucial for long-exposure astrophotography. The QHY183C features a powerful dual-stage thermoelectric (TEC) cooling system capable of reducing the sensor's temperature to -40°C below the ambient air temperature. This aggressive cooling lowers dark current, a major source of thermal noise, to 0.0024 e-\/pixel\/sec when the sensor is at -15°C. This allows you to take multi-minute exposures without being overwhelmed by thermal noise.\u003c\/p\u003e\n\u003cp\u003eTo help prevent dew on the chamber window, heating elements are built into the light shield just above the chamber.

class=\"Apple-converted-space\"\u003e\u003c\/span\u003eAdditionally, the already low thermal noise is reduced even more by QHYCCD’s proprietary thermal noise reduction technology that does not affect the accuracy of the raw image.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eAmplifier glow can also be an issue with some CMOS cameras, but this new QHY model boasts the rare capability of zero amplifier glow, no matter how long the exposure.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe image output is a true raw image, without any internal processing for maximum flexibility with image processing software.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eOther features include a 128MB image buffer that helps tremendously with slower computers using USB 2.0, and when running multiple cameras using the same computer.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe optical window has built-in dew control and the chamber is protected from internal humidity condensation.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eIn addition to AR coating on the optical window, the sensor cover glass and micro lenses are also AR coated for maximum halo suppression.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eThe optical window is AR+AR coated, reducing halos around bright stars.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eIR blocking is not used so that the cameras can be used with maximum sensitivity to H-alpha and near IR light when desired, or a simple IR blocking filter can be attached for typical RGB imaging with IR cut.\u003cspan class=\"Apple-converted-space\"\u003e\u003c\/span\u003eEach camera is carefully calibrated to high precision assuring flatness of the sensor to +\/- 20 microns from edge to edge, eliminating the need for external adjustments by the user.\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 QHY410C'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.
