CG-4 & EQ3, same mount?
Posted 23 March 2013 - 07:15 PM
Are the Celestron CG-4 & the EQ3 the same mount with a different name? I've got an EQ3 & want to put clock drive on it, & I've come across a dual axis set for a CG-4 at a good price. Any thoughts?

They are indeed the very same mount. just a difference in the legs. The drives will work for either.
I have never verified this but if I remember correctly, there were at least 2 versions of the EQ-3 mount and they required different drives.
I have an older EQ-3, its more than 10 years old, it's fitted with Celestron CG-4 drives. The stepper motor drives that are used with these mounts are slow and if there is any slop, they are frustratingly slow. I finally unhooked the Declination drive and replaced it with a slow motion cable.. must faster and more accurate.
If I were to do it over again, I would buy the single axis drive.

Jon. Thanks for the info. Anybody know if this is a fact? I didn't think the design was that old. I thought that before the current EQ-3 design, meant you had a Polaris.
