GM8 adequate for a C 9.25?

Hi, I'm looking for a new OTA for my GM-8 mount. I realize that is the reverse of a normal situation but I have the mount. Currently it holds a 6" Mak and I want more aperture.

Is the C9.25 + GM8 a good combo? What does a C9.25 weigh fully loaded? Are the graphite tubes lighter? I do not do photography but like a steady mount. If the C9.25 is marginal I might go with a 8" reflector for deep sky and keep the MAK for planets.

Thanks for your opinions,

Jim

The GM8 will do for visual use but the 9.25" is going to be a bit shaky if you want to do any imaging. Celestron used to sell the 9.25 on the GM8

If it is any help, I have a metal tube 9.25 on a Meade LXD55 mount. I replaced the stock aluminum legs with some oak ones and that really dampened the shakes. The OTA weighs in at about 25lbs and the whole package, scope,tripod, drives and weights, weighs around 55lbs. I can carry the whole set up out assembled. And the rumors are true, the 9.25 is an awsome scope. Vince

As others have said - Should be fine. Mine is side saddled on a CI-700 with a Megrez 80, and lots of 2" accessories, camera's etc. Rock solid. I use two 25lb CW's, but it's overkill (they are racked fairly far up the shaft). My guess depending on the accessories 25lb would be minimum and 30 best.
