GoTo mount for classic OTA - Help!
Posted 01 May 2009 - 08:11 AM
Or perhaps a simple GoTo Dobsonian mount would suffice as well. At this point, the important thing is the ability to slew and allow visual astronomy to be performed with it. The original Astrola mount is extremely stable and completely amazing as an observatory mount, but that's not what I am after.
I'd like to hear what others have done with larger newtonians and GoTo and help get pointed in the right direction - no pun intended.

With a full-thickness mirror and fiberglass tube, it's nothing like the lightweight OTAs that Celestron and others put on those mounts - which are underkill themselves, IMHO.
You might look at a Sidereal Technology goto servo kit for the Astrola mount. You can do it yourself for about $800, or pay to have it done by someone like Lenord Stage at gototelescopes.com. I think his website even has a pic of a converted Cave mount.
Please don't make a dob out of a Cave. Somehow that seems wrong to me (seriously, do what you want, I'm just ranting! )

Still would be nice to have these optics on a GoTo mount. At least I know what the OTA is capable of. No I don't want to make this into a Dob, but if I could get a Dob mount for this OTA I could still also use it on the GEM at home, the Dob out on "the road."

As many have mentioned, the least expensive route you can take is to upgrade the electronics on your current mount. However, if you're planning up buying a new mount, a CG5 won't do it. I have a 10" f/6. On the Tak EM-200 mount it is barely usable for visual use. It works, but is wobbly:
When I slap it on the 1200, it's quite usable:
Big newts like big mounts. You're probably better off just upgrading your current mount, unless you're ready to fork out some serious cash...
