Review: An excellent telescope - I decided to upgrade from a Skywatcher 130 (a good beginners scope) and have found it well worthwhile. It arrived very quickly and well packed from Green Witch. The supplier has helped me with a small problem I thought I had (that turned out to be a misunderstanding on my part) and I am grateful for their excellent service. The scope is solid and robustly made - I am reasonably fit though wouldn't like to risk my back with any of the larger models - this one is quite heavy enough thankyou! - and it sits firmly on the tripod. Setting up the guidescope was easy though I may also attach the smaller guide scope from the Skywatcher for rough alignment. The control system (GPS, GOTO, huge object database) is not difficult to set up and is truly stunning, taking all the hard work out of finding and tracking targets of any brightness. Great to be able to pick out nebulae, double stars, planets etc from the list and let the CPC800 do the rest. you get a pretty good 40mm eyepiece with it which gives about 50 mag. I am also using the 24 and 10mm and 2xBarlow that came with the Skywatcher but will probably look for some better quality ones in the future. The only minor issue I've found is that the lead for the 'car battery' power supply (I use a Skywatcher 7Ah power tank) plugs into the scope base and has a screw thread to secure it - but it doesn't quite engage in the socket on the scope. However, all in all this is a brilliant quality, easy to use, telescope and good value for what you get. At some point I would like to do some astroimaging but I believe it may be necessary to purchase a wedge to convert the Altazimuth mount to Equatorial for this purpose. Review: An excellent telescope - This is an incredibly well-made device. Anyone who has ever used a simple telescope will be familiar with the two greatest problems: a tripod that vibrates and using two knobs on stalks to keep the object in the centre of the eyepiece. The tripod used with this telescope is heavy and rigid, 14.5kg of die-cast aluminium with stainless steel tubes; I have not noticed any vibration. The telescope is motorised and keeps the object centralised. Setting up the telescope took some time. Once the tripod is levelled, lifting the telescope into place can cause difficulties if you are alone as a central peg on the tripod has to locate in a hole on the underside of the base of the telescope. With some practice, and looking around the base for symmetrical placing of the tops of the tripod legs, this will become easier. One rotated into place, three bolts hold the telescope in position. Engage all three bolts before tightening them. They are captive bolts and they are sprung too, so when dismantling you feel when the bolts have disengaged. The telescope is heavy (22kg) so hold the telescope close to the body when lifting it into place. The sighting scope (9x50) is good for terrestrial use but can be a nightmare for use at night. A 'red spot' sight is much easier to use when aligning the telescope. I had some difficulty at first and found that the GPS system thought that I was in California rather that west Wales. I had to go through the computer menu to switch off the GPS and then switch it back on again to get the correct setting. A session in daylight in order to line up the sighting scope or red-spot finder and also to familiarise yourself with the computer menu is a good idea. The CPC 800 is a joy to use. The motors are very quiet and move the telescope very smoothly to your target. You may have a few people waiting to look, and not having to twiddle any knobs in between is sheer bliss. It is, as I said at the beginning, a very well-made machine that is a delight to use. The telescope is packed in two large boxes because of the weight of the tripod and the heavier optical tube assembly and base. These can become separated in transit. Be patient, it is worth the wait. ## Features - Optical Design 8 inch Schmidt-Cassegrain - Focal Length 2032mm F/10 - SkyAlign Alignment Technology Fast, easy alignment.

It's possible to use a more powerful lens to make Pluto larger but you will definitely loose detail with a more powerful lens. If you expect to see surface detail...you need a much larger scope...possibly an 18 inch or bigger. **Q: I'm very new to the hobby and recently received the CPC 800 as a gift. Can someone recommend what I should buy to magnify the stars and planets** A: To calculate magnification, divide the focal length of the telescope (2032 mm for the CPC 800) by the focal length of the eyepiece. If you also add a Barlow to the eyepiece, multiply the result of the preceding step by the Barlow's magnification (some Barlows magnify more than 2x). The most optimistic rule of thumb I have seen for useful telescope magnification is a maximum of 60x per inch of aperture (480x for the CPC 800), but this requires perfect skies and a perfectly collimated telescope. I prefer to think in terms of 50x per inch (400x for the CPC 800) as the maximum for my best observing sites and 30x-40x per inch (240x-320x for the CPC 800) for my usual observing sites. If you magnify too much, the image becomes "mushy" and you can actually lose detail.For planets and the Moon, I typically use a 13-mm TeleVue Ethos, which gives 156x on the CPC 800, and an 8-mm TeleVue Delos, which gives 252x. My usual observing sites are in California's San Joaquin Valley and range from urban to suburban to semi-rural to rural, but are all below an elevation of 600 feet and are often compromised by haze/smog. A magnification of 250x is about all these skies can handle, and sometimes even 200x is too much. Two months ago, from a local shopping center under better than normal skies, I was able to clearly see Hadley Rille and other major features around the Apollo 15 landing site with my 8-mm eyepiece.On the other hand, the high-elevation dark sky sites that I use in the summer (6500 ft to 8200 ft elevation and Bortle Class 1-2) can often take well more than 250x with the CPC 800. Adding a Barlow to the 13-mm gives me 312x and nice views. Adding a Barlow to my 10-mm Vixen Lanthanum (which usually stays with my 5" scope) gives me 406x, which has been marginal to OK for me. I have Barlow'ed the 8-mm, but 504x on the CPC 800 was too much the one time I tried it.No matter how much you try to magnify the stars, they will still be pinpoints in the CPC 800. It takes professional observatories (sometimes with interferometers) to resolve the handful of nearby large stars into anything more than a dot. However, high magnification is useful for splitting tight double stars. The theoretical maximum resolution of the CPC 800 is 0.69 arcseconds (Rayleigh Criterion) and 0.57 arcseconds (Dawes Limit). Rayleigh is equivalent to true separation, while Dawes is equivalent to the beginning of separation. As a practical matter, I suggest figuring on 1 arcsecond for typical good conditions and maybe 1.5 arcseconds or less for worse conditions. BTW, 1 arcsecond is the angle subtended by a lunar crater about 1.16 miles across (based on the average center-to-center Earth-Moon distance of 238,900 miles).I hope this helps. **Q: How much does it weigh???** A: I have had this scope since 2007. As Rita mentioned above, the total telescope kit weighs 42 lbs. It is NOT 60 lbs, or 65 lbs, or 95 lbs. IIRC, the tripod weighs 19 lbs and the forks/scope weighs 23 pounds. Both pieces are VERY manageable. The forks/scope is much easier to handle than the equivalent Meade. Both of the Meade's handles are mid-way up the fork arms, but on the CPC the "handle" for the left fork arm is under the base of the arm and this makes it much more steady to move and mount on the tripod. **Q: I noticed that the HD version has updated gears and drive. Does this version have it as well? Is there really THAT much of a difference between the** A: While the CPC 1100 I bought a year ago is not the new improved version, I'm not sure if the extra cost is worth it for more casual observers. The improvements they made are significant, but you're probably only going to notice them if you do long exposure astrophotography where you're going to be tracking an object for many minutes at a time and require rock-steady alignment. If astrophotography is what you're interested in, you don't want an alt/azimuth mount like this in the first place, you want a German equatorial mount (called a GEM). In order to do long exposures with my scope you'd have to add something called a wedge, which will set you back another $300 or more. That allows you to do polar alignment for long exposures. While there are wedges available for this scope that will do the job, I don't recommend using them for scopes this big and heavy. Wedges are fiddly things at the best of times because they put the scope in an awkward and sometimes unstable position, and are difficult to get aligned properly. For astrophotography I'd recommend you get a GEM to begin with.As for the optics, the new glass is certainly an improvement, but again, it depends on what you plan on using the scope for. Visually the images through my CPC are absolutely outstanding even in my light polluted area, and it will certainly do a good job for astrophotography. But the upgraded glass appears to have better image quality at the edges of the field of view. ## Customer Reviews ### ⭐⭐⭐⭐⭐ An excellent telescope *by N***B on 21 June 2013* I decided to upgrade from a Skywatcher 130 (a good beginners scope) and have found it well worthwhile.

Would be really exellent If tracking could be cured. I believe there are a great many in use around the world, maybe I was just unlucky. I have other Celestron products with no problems at all. ## Frequently Bought Together - Celestron Cpc 800 XLT Computerized Telescope w/Tube and Tripod - Celestron – NexYZ – 3–Axis Universal Smartphone Adapter for Telescope – Digiscoping Smartphone Adapter – Capture Images and Video Through Your Telescope or Spotting Scope - Celestron 94303 1.25 inch Eyepiece & Filter Kit - Includes 14 Pieces in Metal Foam-Lined Carry Case, Silver --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/52156144-celestron-cpc-800-gps-xlt-computerised-telescope](https://www.desertcart.co.uk/products/52156144-celestron-cpc-800-gps-xlt-computerised-telescope) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-18*
