Celestron11074XLT CPC925 GPS Computerized Telescope

Le seul défaut que je lui trouve : son encombrement.Novice, il s agit de mon premier télescope. Le rendu me paraît très net et très lumineux.J apprécie la localisation automatique et le suivi automatique des astres.Je reste surpris de l ergonomie des logiciels tout comme de l utilisation de port série rs232. C est une recette réchauffée de plus de dix ans.

this is an awesome piece of kit,solid tripod,nil vibration for pics etc,if you're looking for a new scope this one i would recommend although it's not for the fainthearted as it weighs a lot.!!!!!!

This is by far the most expensive telescope I've bought so far, and replaces a 5" Newtonian that cost about $300 a few years back. I've taken it out for a small number of long observing sessions, all in the summer of 2013, with the last one in the clear skies of Yosemite state park. I've been using telescopes for about 15 years on and off and would rate my familiarity with the subject as intermediate - definitely not an expert!First up, the mount is sturdy, easy to use and gives great vibration suppression performance. It easily handles the weight of the 9.25" OTA, and has a handy spirit level built in to make it easy to level the scope. Once the scope is set up, vibrations are quickly suppressed, with the image always returning to visual stillness within a couple of seconds even for harder knocks.The OTA itself is aesthetically well designed, and the carrying handle on the side is extremely welcome. It's not light, but I'm able to set everything up unassisted without too much difficulty (I'm in my late 20's and of very average fitness!). I was a little freaked out at the prospect of having to remove a couple of screws from the OTA to attach the finder scope, but once I confirmed that was indeed what you're supposed to do it went on just fine.So far I've aligned the scope with the 3 star method each time. This allows you to point the scope at any 3 of the 80 brightest objects in the sky and have it automatically figure out what it's pointing at. You have to be fairly precise when you aim the scope at those 3 stars - I've had the alignment process fail a number of times when I've not lined things up precisely enough.Along with the scope itself I ordered the following accessories:* Celestron 2" eyepiece and filter set - $220, mandatory. This kit is an absolute no-brainer. While 2" eyepieces are more expensive that 1.25", the visual experience is much better, and they're just much more satisfying to hold. This kit gives you 3 great 2" eyepieces, a 2" diagonal and a 2x Barlow lens. I have some higher power eyepieces but honestly I rarely use anything but the contents of this kit* Celestron battery pack - the scope requires power if you want to use the GOTO features. I ran it from my car the first time but the dashboard lights attracted every moth and mosquito ever born. And I was perpetually paranoid of killing my car battery in the middle of the night in the middle of nowhere. This pack solves all that, and was easily able to cope with a 5 hour observing session last weekNow onto the scope's performance. At 9.25" there' plenty of collecting and resolving power at your disposal. Uranus was clearly resolved into a disc, and Neptune was just within reach too, though I had to gaze at it for a long time to convince myself I was seeing it. Binaries down to 1 arc second are clearly split, and focus across the field is good.Nebulosity is apparent in several structures - the dumbbell nebulae look great, and the pinwheel galaxy demonstrates significant structure in its arms. The ring nebula in particular looks stunning.I've not had a chance to look at Jupiter, Saturn or any of the winter constellations yet but based on what I've seen so far I'm extremely happy with the purchase and can't wait to see what else it has in store for me.

The original CPC was so easy to use; I could observe objects with the whole family. Set-up was easy; it found every object I wanted to observe. But the corrector plate on the unit I owned had obvious flaws (streaks, bubbles, spider web-like structures); I returned the product. I am waiting for Celestron to release a CPC with the new Edge HD design.

My telescope arrived damaged. Not shipping damaged, but defective.I contacted Celestron and they instructed me to take the telescope apart, remove a part, and reassemble it for shipping. I had to repackage it and send it to their repair department.Their department received it on the 23rd of January and they STILL have it. It's now Feb 25th.I bought a BRAND NEW telescope and I have yet to use it. They told me that their repair department has up to 30 days to process a repair. Or what? Nothing. I call and they simply tell me that I have to keep waiting. There is a line. Wait for an email with your shipping information. No consolation prize, no rush on the repair, NOTHING. Simply, too bad, you have to wait longer.Not only that, but their customer support line services the entire world. They even tell you that when you call. So the wait time can be extremely long.If I knew this is the customer service process, I would not have bought this product. The telescope is no doubt a great one. I just wish I could have found out by now. Unacceptable customer service that I have no choice but to accept.If customer service is anywhere near the top of your list, do not buy from Celestron.
