Customer Review: All around terrific scope!
Although I didn't purchase my CPC 1100 through Amazon.com, I wanted to add my two cents about this great scope. Like the first reviewer, I'm a visual observer only; don't have the time or inclination to mess about with cameras and laptops. I've also owned a few other SCTs over the years and really enjoy this type of telescope. First, it is a heavy telescope. The tube and fork assembly weighs 65 lbs. Make sure you can lift and maneuver something that heavy before ordering one! Although, the ergonomics of the carrying handles make lifting and handling the scope much easier than they would be otherwise. One feature I enjoy with this scope, and another computerized Celestron I used to own, is that unlike their main competitor--Meade--you don't have to do an initial motor calibration. With the Meade SCTs you have to "train the drive" before using the scope for the first time. That's a tedious procedure that must be done outside during daylight, in order to calibrate the motors and hand control. There's no such procedure with the CPC. The first time you set it up at night you're good to go! Now, I live in light-polluted Central Florida. This scope actually can show me some of the brighter deep-sky objects fairly well. Because it has a long focal ratio (f/10), with any given eyepiece you get a nice "close-up" view. This is especially nice when viewing the planets. My favorite objects to view with my CPC, however, are the magnificent globular clusters! Wait until you view M13 or M5 with a 24 or 26mm eyepiece! These objects alone make the telescope well worth it! I find the NexStar hand control menu very easy to navigate, once you practice with it. (And you'll be a "pro" at it your first couple of nights!) There are many nice features here as well: You can control the brightness of the red backlit keypad and display window. The scrolling display can be speeded up or slowed down. You can choose a particular constellation and let the scope show you a number of different objects located there. The "sky tour" feature is a fun way to sample various objects visible overhead. And there are other nifty features. Since I know most of the bright star names, I don't use the "Sky Align" three-star alignment set up. I use the "Auto Two-Star" alignment, which I find easy and quick. Also, you can set up the scope before full darkness and get it aligned if the Moon or bright planet is visible by using the "Solar System Align" method. Very easy! If you're looking for a large aperture scope that performs extremely well on all types of astronomical objects (and are fit enough to handle the 65 lbs!), the CPC 1100 is just what you need!
