convert Celestron Ultima 9.25 to GOTO

Posted By Jay Mlazgar

About 7 years ago,I bought a used Celestron 9.25 Ultima (not Ultima 2000). I have recently moved and now can not keep the mount in a permanent location, so have to polar and drift align every use. That is not practical, and was wondering if the mount and tube can be refitted to a new fork assembly and controller that would allow "GOTO" function. The tripod is solid, has the wedge, and the tube optics are fine. maybe a dumb question, but had to ask.
Thanks!

Ultima 9.25 power supply

Posted By Jay Mlazgar

Does anyone know "definitively" where I can buy a 110 volt to 12 volt power supply that will work with my Ultima 9.25? This is not an Ultima 2000, and I think it came out after Ultima 8 and was just called "Ultima 9.25."
It is a connector that is approximately 3.4 to 3.5 mm. I bought a jack of all trades Radio shack. Their "cylindrical adapters" are 3.7 mm and 3.2 mm.

They do have a "mic jack" type connector that is 3.5. I don't know which type the Ultima originally took.

please help.

Also don't know how to get in to change the battery. The original owner said it was sort of a pain.
Thanks!
