The Celestron CPC Deluxe 800 HD telescope has the most talked-about improvement in optics in years - Celestron's EdgeHD flat field optical system - a Sky & Telescope Hot Product for 2010.

With Celestron's renowned Starbright XLT multicoatings on every optical surface, the EdgeHD optics give you maximum light throughput across the widest possible visual and photographic spectrum. The CPC Deluxe 800 HD's light grasp of almost 850 times that of even the sharpest dark-adapted eye can reveal to you star clusters, nebulas, planets, and galaxies in amazing visual and photographic detail.

Those award-winning EdgeHD optics are mounted on a newly-upgraded Celestron CPC go-to mount with SkyAlign and GPS that makes finding over 40,000 of those stars and objects easy and automatic. You spend more time looking at celestial objects, rather than looking for them.

The sensible price of the CPC Deluxe 800HD with EdgeHD optics and Starbright XLT coatings makes true astrographic-quality imaging and visual astronomy available at a reasonable price for almost everyone. Its light weight and easy two-component assembly make it a pleasure to set up and enjoy - either in your back yard or at a distant dark sky site. The new EdgeHD CPC Deluxe 800 HD is an optically and mechanically advanced telescope that virtually any beginning or advanced astronomer can afford and enjoy.

This Telescope's Optical System . . .

EdgeHD Schmidt-Cassegrain optical tube: 8" aperture (2032mm focal length f/10). Dual-element Schott glass field flattener lens permanently mounted in the central baffle tube. Guaranteed diffraction-limited optical performance, free from coma and corrected for spherical aberrations (aplanatic design). The optical design is a Sky & Telescope Hot Product for 2010. For more details, click on the "EdgeHD optics" link in the support tab above.

Starbright XLT fully-multicoated optics: This high transmission/high reflectivity optical multicoatings package is applied to all optical surfaces. Starbright XLT coatings give you visibly higher light transmission for visually brighter deep space images and shorter exposure times during imaging. They also increase the contrast on subtle lunar, planetary, and nebula details when compared with a scope with ordinary coatings or multicoatings. For more details, click on the "Starbright XLT" link in the support tab above.

Tube vents: Two cooling vents located on the rear cell allow warm air to be released from behind the primary mirror when the scope is taken out for a night's observing or imaging. This shortens the amount of time needed for the optics to cool down to ambient air temperature for peak optical performance. Each vent has an integrated 60 micron micro-mesh filter guaranteed to let warm air out without letting dust in.

Fastar compatible: For the ultimate in wide-field catadioptric imaging, the EdgeHD optical tube is Fastar and Hyperstar compatible to allow CCD imaging at a blazingly-fast f/2 focal ratio. An optional Fastar/Hyperstar lens assembly replaces the telescope's removable secondary mirror (an exchange that takes only a few minutes). Your CCD camera is attached to the Fastar lens. This puts your camera at the f/2 position in the center of the Schmidt corrector lens at the front of the scope, rather than in its normal f/10 position at the Cassegrain focus at the rear of the scope. 

Focusing: Focusing is accomplished by turning a knob at the rear of the scope body that moves the primary mirror fore and aft along a central baffle tube to adjust the focus. The Celestron focusing mechanism is supported by two pre-loaded ball bearings, minimizing the "mirror flop" typical of bushing focus mechanisms that causes image shift during critical focusing.

Mirror support knobs: Mirror support knobs hold the mirror in place after correct focus is achieved for imaging and reduce image shift when rotating the tube around the mount (while moving past the zenith during astrophotography, for example). Unlike other designs that have only one locking knob located off to one side of the mirror, the Celestron system uses three locks equally spaced around the mirror to distribute the mirror locking force symmetrically. The focuser itself acts as one of the locks, while two knobs spaced 120° away in either direction act as the second and third locks to hold the mirror in place without putting any asymmetrical force or pressure on the mirror. This keeps the image centered in the eyepiece (or on the CCD chip) no matter what the orientation of the optical tube.

Finderscope: 50mm straight-through achromatic design, mounted in a spring-loaded easy-adjust quick release bracket.

Visual back: Removable 1.25" visual back holds visual accessories such as star diagonal, tele-extender, etc.

Star diagonal: 1.25" multicoated prism type.

Eyepiece: 1.25" 40mm Plössl (51x). The eyepiece field of view is 0.8 degrees, over one and a half times the diameter of the full moon, for bright wide-angle deep space views.

This Telescope's Mount . . .

Fork mount/drive system: The heavy-duty die-cast aluminum dual fork arms are rigid and damp vibrations quickly. Carrying handles are built into the fork arms. There's a convenient detachable mounting bracket for the NexStar computer hand control that lets you use the hand control and view information on the two-line display hands-free while using the scope.

The redesigned and re-engineered drive train of the CPC Deluxe mount includes DC slewing/tracking motors with encoders in both altitude and azimuth. Motor resolution is 0.14 arc seconds. The redesigned electronics deliver constant regulated power to the motors, making them capable of driving the telescope smoothly, even when it is not perfectly balanced, and without sacrificing smooth tracking motion and pointing accuracy across the entire sky.

The new larger 6" diameter 180-tooth brass altitude and azimuth drive gears are driven by new 0.75" stainless steel worms in spring-loaded worm blocks to provide smooth slewing and tracking. There are 9 user-selectable speeds from 3° per second slewing down to a precise 0.5x sidereal rate for photographic drive correction. The drives work in the altazimuth mode (right/left up/down) to locate and track objects for visual use and casual solar system photography. If long exposure deep space photography is planned, the scope can be converted to equatorial operation by adding an optional wedge.

The fork arms and optical tube are supported by a unique roller bearing system that uses both steel and nylon ball bearings rotating around a large 9.8" azimuth bearing track designed to provide an ultra-stable and smooth polar axis motion and smoother tracking accuracy for long exposure astrophotography.

The scope includes three preprogrammed drive speeds - sidereal, solar, and lunar. It operates in an altazimuth mode, as well as northern hemisphere equatorial and southern hemisphere equatorial (using an optional equatorial wedge).

The scope is powered by external 12 Volt 2.5 Amp DC power (a car battery or optional rechargeable 12V battery #4517V). The scope cannot be powered by short-lived flashlight batteries. The standard equipment car battery cord and optional AC adapter plug into the drive base. Power and command signals to the declination motor are routed through cordless internal slip ring signal paths. There's no separate external declination cable to connect the drive base to the dec motor as with other scopes, so you don't have to worry about losing a cable or breaking it by tangling the cable around the scope inadvertently while observing.

NexStar Computer: The scope's NexStar computer can show you the planets and thousands of deep space objects at the touch of a button or two the very first night you use your scope - even if you've never used a telescope before! The Celestron CPC's built-in GPS system and easy-to-use SkyAlign software will have you lined up on the sky and observing in minutes. For information on many of the features and capabilities of the NexStar computer and the unique SkyAlign software, click on the "NexStar computer" link in the support tab above.

NexRemote software: NexRemote telescope control software allows you to control the CPC Deluxe 800 HD from your personal computer or laptop. NexRemote provides full emulation of every aspect of the Celestron computerized hand control. It lets you align in any tracking mode; go to any database object; setup user objects; put the scope in hibernation; connect to popular planetarium programs; etc.

In addition to emulating the NexStar hand control, NexRemote adds powerful new features that let you keep your eyes on the stars instead of the LCD by enabling talking computer speech support using your computer's built-in speaker. You can control the objects you want to see and the order that you see them; create and save custom tours by launching NexTour; take wireless control of the telescope with optional gamepad support; connect your personal GPS device to NexRemote using NexGPS; download NexRemote updates online to add the latest features; and more. The NexRemote software includes an RS-232 cable to connect the CPC Deluxe 800 HD to a PC.

Adjustable height tripod: The new heavy duty tripod has 2" diameter steel legs. It has a metal lower tensioning spider and an upgraded aluminum upper center leg brace for rigidity and rapid vibration dampening. The leg brace also doubles as an accessory tray with holes to safely hold eyepieces up out of the dew-soaked grass and close at hand. A locating pin on the top of the tripod automatically centers the scope on the tripod for easy assembly in the dark. A single hand-tighten lever per leg locks in the tripod height adjustment. The levers are on the insides of the legs, to avoid snagging on clothing in the dark. The tripod adjusts in height over a 30" to 45" range.

Two-year warranty: All Celestron go-to telescopes have a two-year warranty

This is a great scope that is very stable, attractive, and good optics. It may seem to be an expensive scope for a beginner, but it is simple to operate and is powerful enough to let you explore the hobby without feeling that you should have something bigger or more sophisticated. I recommend it to anyone that wants to seriously indulge in amateur astronomy.

Hi, I purchased my CPC 800 a few months ago as I wanted to do some planetary and deep space astro photography. I also purchased the Celestron Wedge for my CPC and was very impressed with its functionality and ease of use. For deep space photography I am using a Canon 450D currently but am looking to upgrade to the Starizona Hyperstar attachment and a CCD camera next year. I have found the computer based software installed into the CCP invaluable for skywatching as it saves me loads of time when I can just enter the star number and go-to straight away. In my opinion a great telescope for beginner and expert alike. (Posted on 11/17/2018)

I have had my scope since December 2012 and absolutely love it. I took months to narrow down what it was I really wanted, and once my son and I visited Astronimics in Norman, Oklahoma I was greeted with more info which lead to a reavaluation of what I whated and my final selection. After looking for hours at all displays I was finally torn between the CPC 925 Edge HD and the CPC 800 Edge HD. I wanted a high quality device and something that I could handle on my own, and because of the lower weight I selected the CPC 800 Edge HD, and I could not be happier with my choice. I have learned that no scope can do everything great so I wanted one that could be used for both visual and astrophotography and still get very good results. For visal it is superb and it is very good for limited Astrophotography, very good if you mount on a wedge. The quality of the CPC Edge HD scopes are top notch and the views across the entire FOV is fantastic. My only con about the scope is the finder scope included, quite simply un-useable for me, just could not see through it hardly at all. I upgraded mine to a Stellervue 9X50 Illuminated Right Angle Finderscope and my issue was resolved. I have been involved in the hobby for a little over 10 years and owned a Celestron Nexstar 80 Goto in early 2000s. I sold it several years ago and wanted something larger that will allow me to see more, and more it has. I have successfully taken photos and they have turned out very good for a beginner, and visually it is one of the nicest I have ever looked through. I spent several hours in Astronomics and was allowed to look at dozens of scopes and when I had a question the staff were very happy to answer my inquires. They have a huge selection and a large price range to choose from, and it was nice to be able to put my hands on so many different scope types at one place.

So I highly recommend this product and I highly recommend that if you can please visit Astronomics and feel very assured if you purchase from them.
