Average Reviews:
(More customer reviews)This is a very nice telescope. I have been using it the past week and have viewed the Moon, Venus, Jupiter. Overall the optics are excellent. But there are a few issues, which had I known earlier I may not have purchased this scope.
1. Celestron advertises that the scope can be used with 8 AA batteries. This is not completely true. The batteries drain very quickly and will probably not even last one viewing session (say 30 mins).
2. Without power the telescope cannot be moved along the azimuth (left-right direction). So you cannot use it at all.
So essentially if you want to take this telescope out of the city to some dark sky location you have to buy a powertank (or maybe run it off your car). I would have liked a design that allows me to use the goto feature when I want it but still be able to slew the telescope manually, without power.
Why do I still give it 3 stars. Well, Celestron tech support is very responsive (over e-mail). The telescope itself is excellent (optically). I have gotten very good views of planets. It has been a little too cloudy and light polluted (I live in a city) for me to try seeing nebulae.
Details:
The DC motors that slew the telescope are very sensitive to the voltage and current of the power supply. If you use the telescope for 20-30 minutes after that the batteries drain down and the scope becomes unusable (till you replace the batteries of course). Celestron tech support told me that they recommend using the battery only as an emergency back up!!! Strange that they don't mention on their website that batteries are only for "backup" and you have to run the telescope on wall socket, or a "power tank".
