Description

Best Telescope for Imaging: Celestron Advanced VX 8" EdgeHD Telescope
Get the features and performance of a top-of-the-line imaging setup at a fraction of the cost with the Advanced VX 8” EdgeHD Telescope. For our money, it’s the best portable imaging rig available—and best of all, it’s priced under $3,000. Let’s start with the mount: engineered from the ground up for imaging, Advanced VX includes all the same features of Celestron’s flagship CGE Pro mount, but sized for payloads under 30 pounds. You’ll get permanently programmable periodic error correction for dead-on tracking accuracy, integer gear ratios, and an autoguider port. Plus, Celestron’s All Star Polar Alignment procedure is built into the hand control. Even if you don’t have a clear view of Polaris, you can align to the North Celestial Pole for long exposure astrophotography in just a few minutes. When it comes to optical performance, Celestron has you covered. The 8” EdgeHD optical tube delivers edge-to-edge sharpness across DSLR sensors and the largest CCD chips. Plus, you can configure this versatile system for imaging at three different focal ratios: place the camera at prime focus to image at f/10, use a custom-made EdgeHD focal reducer to reach f/7, or attach a Hyperstar lens assembly to the front of your telecope for ultra-fast f/2.2 wide field imaging. The Advanced VX does it all without compromise. All you have to do is capture your cosmic masterpiece.

EdgeHD CG-5 8" f/10 Aplanatic Schmidt-Cassegrain Telescope (OTA Only)
Engineered to deliver sharp and clear distortion-free views, the Celestron EdgeHD CG-5 8" f/10 Aplanatic Schmidt-Cassegrain Telescope is an ideal choice for observation, astrophotography, and imaging objects within or beyond our solar system. It features an aplanatic Schmidt-Cassegrain optical system consisting of a corrector plate, a spherical primary mirror, and a secondary mirror along with a set of field-flattening lenses integrated into the baffle tube. Complementing the EdgeHD system is the proprietary StarBright XLT optical coating system, which improves light transmission and reflectivity across the entire visual spectrum. The combination of EdgeHD and StarBright XLT produces bright and clear high-resolution images with true color rendition across the entire field of view without distortion, aberrations, or off-axis comas.
Optimized for imaging, the internal focusing system features mirror support clutches to ensure proper alignment and mirror locks to avoid accidental defocusing during long-exposure astrophotography. The optical tube is outfitted with a standard 1.25" visual back to make it easier to find eyepiece, accessories, and imaging gear. For visual observations, a 1.25" star diagonal is included along with a 40mm Plössl eyepiece that yields 51x magnification. The EdgeHD 8" is offered here without a mount or tripod for users who already have a reliable support system and are looking to upgrade or add to their existing gear, but comes with a standard-sized CG-5 dovetail plate that is compatible with Vixen-style saddles.
Optical Tube

8" (203.2mm) aperture
f/10 focal ratio
2032mm effective focal length
Aplanatic Schmidt-Cassegrain optical design
EdgeHD field-flattener aplanatic design eliminates spherical aberration, field curvature, and off-axis star coma to improve resolution, sharpness, and clarity across the entire field of view - especially at the edges
Diffraction-limited SCHOTT glass reduces internal light loss to improve color, clarity, and sharpness
StarBright XLT optical coatings
Flexible tension clutches hold the primary mirror in place to reduce image shift without putting any force or pressure on the mirror assembly, keeping subjects centered
Internal mirror locks prevent accidental adjustment to focus - important during long-exposure astrophotography
Integrated 95-micron mesh filter allows hot air to be released from behind the primary mirror without dust getting in, to prevent mirror distortion due to uneven surface temperatures
Resolution: 0.69 arcsec (Rayleigh); 0.57 arcsec (Dawes)

Advanced VX GoTo German Equatorial Mount
Engineered and optimized for astrophotography with mid-sized optical tube assemblies, the Celestron Advanced VX GoTo German Equatorial Mount delivers the performance required for clear images through the use of dual-axis low-cog DC servo motors and backlash compensation. Added to this are encoders on the motors and Permanent Periodic Error Correction (PPEC) which help to improve positioning and tracking precision and ensure your target object stays centered for long-exposure photography techniques. Supporting the mount is a large 2" stainless steel tripod that has a wide stance for stability on most terrain, and a center tray that holds 1.25" and 2" eyepieces and accessories and acts as a leg-lock to further stabilize while helping to minimize vibrations.
The brain of the system is the NexStar+ computer controller which is equipped with a database of over 40,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog; it can also be programmed with up 100 custom user-defined objects with filters to create custom object lists. Its intuitive menu-driven user interface makes observing the heavens fast and easy; features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar+ controller an invaluable tool to new users and experienced star-gazers alike.

Based on Astronomy magazine's telescope "report cards", scopes of this size and type generally perform as follows . . .
Terrestrial Observation: Observing terrestrial objects (nature studies, birding, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial observing. Scopes with apertures under 5" to 6" are generally most useful for terrestrial observing due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes.	No
Lunar Observation: Visual observation of the Moon is possible with any telescope. Larger aperture scopes will provide more detail than smaller scopes, thereby getting a higher score in this category, but may require an eyepiece filter to cut down the greater glare from the Moon's sunlit surface so small details can be seen more easily. Lunar observing is more rewarding when the Moon is waxing or waning as the changing sun angle casts constantly varying shadows to reveal craters and surface features by the hundreds.	Great
Planetary Observation:	Very Good
Binary and Star Cluster Observation:	Very Good
Galaxy and Nebula Observation:	Fair
Photography:	Yes
Terrestrial Photography: Photographing terrestrial objects (wildlife, scenery, etc.) is usually possible only with refractor and catadioptric telescopes, and convenient only when the scope is on an altazimuth mount or photo tripod. Most reflectors cannot be used for terrestrial photography. Scopes with focal ratios of f/10 and faster and apertures under 5" to 6" are generally the most useful for terrestrial photography due to atmospheric conditions (heat waves and mirage, dust, haze, etc.) that degrade the image quality in larger scopes.	No
Lunar Photography: Photography of the Moon is possible with virtually any telescope, using a 35mm camera, DSLR, or CCD-based webcam (planetary imager). While an equatorial mount with a motor drive is not strictly essential, as the exposure times will be very short, such a mount would be helpful to improve image sharpness, particularly with webcam-type cameras that take a series of exposures over time and stack them together. Reflectors may require a Barlow lens to let the camera reach focus.	Yes
Planetary Photography:	Yes
Star Cluster / Nebula / Galaxy Photography:	Yes
