Matt as you might know I own a 10" Lx200. I get good images of the planets, but it cost a lot of time to get the collimation right. Hi res images of the planets must have very good coliimation.

The beauty of the Lx200 is you can set up in about five minutes and get to observing within about 7 minutes. The 9.25 will take a little longer to setup being an eq mounted scope. You can get fork mounted 9.25's but not recommended. Fork mounts do have their advantages but also have some glaring disadvantages.

The Lx200 is from a planetary point of view slightly inferior to the 9.25. Reason also being as those mentioned and the scope has a longer close focusing distance. This makes a big difference. The figure of the primary is also a lot tighter than the 10". Some of the best planetary imagers are using the 9.25"scope. A good example is Damien Peach found here: http://www.damianpeach.com/barbados05.htm Bear in mind that he has very good seeing, but this is still better than my best effort with the LX200 found here:
http://www.iceinspace.com.au/forum/s...ht=jupiter+GRS (look at the second image)

Incidently, recent changes to Celestron structure may have affected manufacturing capabilities.

I did have a link to the Meadelx200 GPS. com but it seems to have changed. If anyone has the updated link, perhaps they can supply it. It is a very useful site and gives an insight into the minor problems the scopes have.

This one is also reasonable: http://groups.yahoo.com/group/LX200GPS/

Best of luck with your decision.
