Celestron EdgeHD 11 OTA
See the Universe in HD
EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view...
True Astrograph Quality
Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.
Improved Performance
Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron’s StarBright XLT optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum.
Mechanical Features
In addition to Celestron EdgeHD 11 OTA optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night.
- Mirror clutches - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor).
- Tube vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in.
- Fastar versatility - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.
Individually Tested
Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This “final acceptance test” confirms the EdgeHD will perform in the field and deliver high-quality astroimages.

The AS1715MC is a sensitive color camera with a 1/2.8" sensor and 8.46 megapixel resolution. With the Sony STARVIS technology used, this camera has low readout noise (0.72e) and ultra-high sensitivity, making it ideal for astronomical imaging of the planets and smaller
deep-sky objects and also for microscope photography.
High Transmission Speed The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR cache to ensure stable and secure
data transmission.
USB 3.0 Port & ST4 Guide USB 3.0 Port: Provides 5Gb bandwidth to allow AS1715MC to run at
45.1fps (10bit, high speed mode). ST4 Port: Can be used to connect with the auto guide port of mount
for guiding
.
Readout Noise Readout noise includes pixel noise, circuit noise, and ADC quantization noise. The lower the readout noise, the better. As can be seen, the readout noise of ASI715MC is very low. As the gain value goes high, the readout noise goes down.
Quantum Efficiency The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and lower readout
noise are necessary to improve the image signal-to-noise ratio. According to our estimation, the QE peak value of ASI715MC is about80%.
Introducing the ASI676MC, the all-sky camera featuring a unique square
1/1.6-inch image sensor and a super high resolution of 12MP! It is perfectly suited for meteor recording and full sky surveillance. The
square format facilitates easier composition, making mosaic stitch simpler and more efficient, and the high resolution brings you clear details of the Sun and our Moon. With this camera, you may start your marvelous journey
to explore the boundless night sky.
Why Square Format?
One of the biggest benefits of AS1676MC's square format is it makes the whole mosaic construction process much easier by eliminating the need to consider the difference between the long and wide
sides of the format during mosaic stitching. Not only that, the square format also makes the AS1676MC more compatible with various types of lenses such as fisheye lenses and wide-angle lenses. Thus,
ASI676MC is more suitable for tasks such as meteor
recording and full sky surveillance.
Starvis 2 Technology
STARVIS is a sensor technology developed by Sony that surpasses the sensitivity of the human eye. STARVIS 2 is an advancement of STARVIS technology,
supporting an even higher dynamic range. With this technology, ASI676MC exhibits lower readout noise and dark current, along with significantly enhanced
sensitivity in the near-infrared spectrum.
No Amp Glow
AS1676MC does not have any amp glow, no matter
how long the exposure and how high the gain value
you set.
256MB DDR3
The camera is equipped with a USB 3.0 transmission interface and a built-in 256MB DDR3
cache to ensure stable and secure data transmission.
Higher QE Lower Readout Noise
The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain. This allows the camera to maintain the same high dynamic range as it does at low gain. When the gain is 180, the HCG mode is automatically turned on. The readout noise is as low as 0.56e, and the dynamic range can still reach a level close to 11stops.
Quantum Efficiency
The QE curve and readout noise are very important parameters to measure the camera's performance. Higher QE and lower readout noise are necessary to improve the image signal-to-noise ratio. According to our estimation, the QE peak value of ASl676MC is about 83%.
Dark Current Noise
The ASI676MC's lower dark current noise means that the image signal-to-noise ratio is also higher, especially when photographing dark objects, it produces images with better sharpness.
IR-Cut Coated Window
ASI676MC is equipped with an IR-cut coated window in front of the sensor, with a diameter of 21mm and a thickness of 1.1mm. It effectively reduces infrared interference and improves image quality.

Simply swivel the telescope to the direction of your intended object and look through the eyepiece. This scope's Teflon bearing system in both axes with tension control handle means you'll be able to smoothly move your telescope to a precise location.
What is a Dobsonian telescope and why the tension control handle?
A simple, elegant form of an alt-azimuth mount made to carry a Newtonian reflector was popularized by John Dobson in the late 1970's. The Dobsonian mounted telescope is popular among amateur astronomers and telescope makers because of its simplicity. In its simplest form, the Dobsonian mount consists of a box which allows the optical tube assembly to pivot in altitude, while the box itself is swivelled on a base in azimuth.
The Dobsonian mount usually relies on the friction between the side bearings on the optical tube of the telescope and a frictional material on the saddle to hold the optical tube in place. If there is too much friction, the telescope is difficult to move to center an object in the filed of view. If there is too little friction, the telescope will not sty where it is positioned. This makes stabilizing the optical tube of the telescope difficult when using a Dobsonian mount, especially when accessories, such as a finderscope or an eyepiece, are added to the optical tube. As long as the amount of friction is at an appropriate level, and therefore stabilization of the optical tube is achieved, the telescope can remain in its desired position to view an object and maintain its position even when the mount is rotated.
The devices for stabilizing a telescope on the Dobsonian mount currently available include: a sliceable weight to counter balance the weight of the telescope, a friction lock that must be adjusted to inhibit movement of the telescope, and a spring attached between the telescope tube and mount to aid in stabilization.
These devices are inconvenient to use because they do not provide a simple and user-friendly way to adjust the friction. The objective of the saxon Tension Control Handle invention is to provide a tension adjuster that users can easily turn to add or reduce tension, thereby increasing or decreasing the friction between the optical tube and the sideboard of the mount.
By providing such a tension adjuster, the telescope does not need to be balanced in order to stay in position. The tension adjuster can be tightened such that the optical tube can stay in a position but can still be moved when prompted to adjust the position of the optical tube. Alternatively, the tension adjuster can be completely tightened to lock the optical tube in position.

- Next-Generation Imaging Sensor for Celestron Origin: Upgrade your system with Sony’s latest Starvis 2 color CMOS technology, offering improved resolution and enhanced sensitivity.
- Compact Pixels, Brighter Images: Small 2.0 μm2 pixels increase resolution while Starvis 2 technology boosts light conversion efficiency. The result: brighter, sharper images with more faint object detail revealed.
- Modern 16:9 Aspect Ratio: A wide, cinematic field of view perfectly matches smartphone and tablet screens, producing images that fill the entire display for a more pleasing view.
- Easy, Tool-Free Installation: Clear, step-by-step instructions guide you through attaching your new camera using Origin’s existing adapter and retaining ring—no prior experience required.
Reveal stunning detail in your deep-sky astrophotography with the Origin 678C—Celestron’s next-generation camera for the Origin Intelligent Home Observatory. Featuring Sony’s latest Starvis 2 CMOS technology, this high-performance camera delivers increased resolution and finer detail thanks to its smaller pixel size and enhanced sensitivity.
The Origin 678C Camera replaces the original Origin 178C Camera, giving you an upgrade in image quality. Whether you're imaging galaxies, nebulae, or star clusters, you'll capture more object detail in images that better fill your smartphone or tablet’s display screen.
It’s the perfect way to further enhance your Origin experience—and your astroimaging.
What’s New with the Origin 678C Camera
The Origin 678C Camera brings meaningful enhancements to your astrophotography experience. Here’s what you can expect:
-
Increased resolution
Although both sensors are the same physical size, the IMX678C uses smaller 2.0 μm² pixels than the 2.4 μm² pixels in the IMX178C. This results in a finer resolution of 1.2 arcseconds per pixel (down from 1.5 arcseconds per pixel), allowing you to resolve more detail and “zoom in” slightly more on celestial objects. This is especially beneficial since most night sky targets are relatively small. -
Larger file sizes
Because the IMX678C packs more effective pixels (8.4 MP vs. 6.4 MP), image files will be somewhat larger. As a result, you may notice slightly slower automatic image processing in the app, depending on the performance of your smartphone or tablet. -
Increased sensitivity
Despite having smaller pixels, the IMX678C is slightly more sensitive overall than the IMX178C. The improvement is subtle; images won’t appear dramatically brighter. -
Different ISO response
ISO values are not directly comparable between the two sensors. The IMX678C's default ISO is 1000, while the IMX178C’s is 200. -
Different aspect ratio
The IMX678C uses a 16:9 aspect ratio, compared to the 3:2 ratio of the IMX178C. This means your field of view will appear more rectangular, ideal for framing larger regions of the sky and perfectly matched to the landscape orientation of most smartphone and tablet displays—making it easier to compose, view, and share your images.
Quick and Simple Installation
Upgrading to the Origin 678C Camera is fast and hassle-free. Designed to integrate seamlessly with your Origin system, the camera installs without any complicated tools or processes. Simply remove the existing camera, attach the Origin 678C using the included adapter and retaining ring, and plug it in.
After you install the new camera, we’ll walk you through capturing new calibration frames. Dark frames reduce sensor noise, while flat frames correct for illumination variations across the image. The Origin app makes this process simple and intuitive—and you can follow along with our video, too.
For the easiest and most consistent results, we recommend the PrimaLuceLab GIOTTO for Celestron Origin— a flat-field generator custom-designed for Origin that works with the same smartphone you use to control Origin. Whether you use GIOTTO or the evening sky (i.e., “sky flats”), capturing new flat frames ensures your upgraded system is optimized and ready to deliver stunning, high-contrast astrophotography from your very next session.
Second Life for Your Origin-178C Camera
Upgrading to the Origin 678C doesn’t mean your original camera has to sit on the sidelines. The Origin-178C is a powerful tool, and now it’s free to be used with other telescopes you may own. With its standard M42 T-thread connection, it mounts easily to most optical systems and makes a great planetary or lunar imaging camera. In minutes, your 178C will be ready for a whole new role in your astrophotography toolbox.

CELESTRON’S BEST OPTICS
What makes the view through a CPC Deluxe HD unforgettable? It all starts with the newest EdgeHD optical system. This unique design corrects for both coma and field curvature, providing aberration-free images and pinpoint stars across the largest imaging sensors and all the way to the edge of the widest eyepieces
Read more about how EdgeHD outperforms competing optical systems by downloading the EdgeHD whitepaper.
All EdgeHD systems include Celestron's StarBright XLT coatings on all optical surfaces for brighter images and increased light transmission. Plus, every EdgeHD optical tube is Fastar compatible. Simply remove the secondary mirror and attach a third party lens assembly and you’re ready to image the night sky at ultra-fast f/2.
ULTIMATE VERSATILITY
Customers and reviewers have hailed the CPC Deluxe an all-around top performer, equally well suited to a star party or a university astronomy course. The beefy dual fork arm mount anchors the telescope for ultra-precise tracking, but weighs just 29 kg and includes rugged carrying handles to make setup quick and easy.
As soon as you turn on your CPC Deluxe HD, you’ll be guided through a simple SkyAlign procedure. The telescope walks you through centering any three bright objects in the eyepiece. From there, it’s ready to locate and track more than 40,000 celestial objects.
To customize your experience under the stars, CPC Deluxe HD is compatible with all of Celestron’s latest accessories. Add StarSense AutoAlign and your CPC will align itself in under 3 minutes. Or add the SkyPortal WiFi Module and control your telescope using a smartphone or tablet.
With this much versatility, the CPC Deluxe HD is a telescope that will serve you well for years to come, no matter what you choose to do with the hobby—including astroimaging.
BUILT WITH IMAGING IN MIND
Most altazimuth telescopes are designed primarily for visual use, but not the CPC Deluxe HD. It offers all the same high-end features you’ll find Celestron's German equatorial mounts. Out of the box, your CPC Deluxe can track accurately for up to 30 seconds without adding a wedge, thanks to a re-engineered drive train with a 6-inch brass gear, stainless steel worm gear, and both steel and nylon ball bearings.
If you’ll be doing longer exposure astrophotography, adding the HD Pro Wedge turns this telescope into an astroimager’s dream setup. With a wedge, you can take advantage of the All Star Polar Alignment procedure, which has you polar aligned in just minutes. You can also train your mount to be even more accurate with Permanently Programmable Periodic Error Correction. Finally, your CPC tracks smoothly through the meridian without doing a meridian flip, enabling you to capture objects in the best part of the night sky.

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 8" Celestron Schmidt-Cassegrain (manufactured 2006 or later), EdgeHD, and the 36cm RASA optical tube, replacing your retaining ring so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).
How it works
The Dew Heater Ring replaces the retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.
Simply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.
The Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.
The Dew Heater Ring comes complete with:
- Dew Heater Ring
- Cable management clip
- Power jack extension cable
- Paper installation shield
Enhance your setup
To achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring’s power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers’ heater output ports, or to a third-party controller’s heater output port. (Note: the ring’s integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).
We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.
The Luminos series eyepieces offer a wide 82º field of view in both high power and low power models, allowing you to make the most of your telescope, whether you own a short, fast refractor or a Celestron EdgeHD telescope. The optical set consists of six or seven elements (depending on the model) and is fully multi-coated for crisp, sharp views. All six Luminos eyepieces are parfocal, which means you can switch out eyepieces during observing sessions with little or no additional focusing required.
The Luminos eyepiece body is made of polished and anodized aluminum. A rubber grip runs around the equator of the eyepiece, giving you a secure grip and an easy method for raising and lowering the retractable eyecup. Simply twist the rubber grip to adjust the height of the eyecup. The insert barrel is threaded to accept filters.

The Celestron Dew Shield DX is an essential accessory that protects your optical tube in the field. It prevents excess moisture in the air from forming condensation on the corrector lens. A dew shield also helps block stray light from entering the telescope for better viewing and astroimaging. Use the Dew Shield DX on your 6” and 8” Schmidt Cassegrain, EdgeHD, and RASA (with single dovetail) optical tubes with confidence.
Construction
The Dew Shield DX provides a perfect, custom fit designed specifically for 6” and 8” Celestron optical tubes. The Dew Shield is built from durable PE plastic that is flexible but strong. Extra padding has been added at the tube attachment edge to create a stronger fit on the optical tube. The felt-lined interior absorbs any additional stray light and excessive moisture, creating optimal contrast when viewing and imaging. The large dovetail cutout has been made both wider- to accommodate a 4” wide dovetail rails, as well as deeper, to create a more solid connection with the optical tube.
Attaching the Dew Shield to your optical tube is easy thanks to the Velcro attachment points. Whether your optical tube is 6” or 8”, simply adjust the Velcro for the correct fit.
Transportation and Storage
To save space when not in use, roll up your Dew Shield DX for easy transport and storage.
