However as I attach more and more accessories(those ones necessary for planetary imaging), it's prone to vibrations(RA motor vibrations). I'd like to know if there is a way to attach my Celestar 8 OTA to a CG-5GT ... BTW, it's on "clearance sale" at OPT ( $ 590.00 ) Perhaps someone could tell me if there's a dovetail that fits my Celestar 8(or any other way). If so, where can I purchase what's necessary to mount it properly on it? Thanks in advance!!

I did see OPT had such dovetails, but I didn't know the CG-5 was a Vixen style one Now, would any vixen style dovetail do the job, or is there any recommended?? Thanks!!!

There is one thing though, my Nexstar8 I tried to remove it from the fork arm & put it on the newer SE mount & got a bar just like you are doing but that scope did not have maching holes to put a vixen bar. So get OPT to look & see if your OTA has holes to put a vixen bar. because the oringinal Nexstar8 was meant for the none removeable fork arm they did not put match holes on the front to back of the ota there were a couple screws holes but it would have been on an angle. Hope that helps Joe Post Extras:       Rusty Postmaster Reged: 08/06/03 Loc: Brooker, FL Re: Old Celestar 8 OTA on CG5?

They should be able to do this if you are buying a bar & OTA. Joe Post Extras:       Qkslvr Pooh-Bah Reged: 06/23/06 Loc: NE Ohio, US Re: Old Celestar 8 OTA on CG5?

Does the job and the 8 OTA is now securely perched atop my newly acquired CG-5 GT. Hope this helps.
