Question about Astromaster RA drive

[Mamsoth]

Hi all, I have been looking at the Astromaster RA drive and it says it will work on cg-2 and cg-3 mounts, my question is will it work on a cg-4 mount? I would really appreciate the help.

Thanks and Clear Skies

I would doubt it. The EQ1/CG2, EQ2/CG3 mounts are fairly similar, the EQ3-2/CG4 is bit different.

I'd doubt it too - the EQ1 and 2 (CG2 and 3) usually have a large toothed wheel arrangement whch the motor engages with and they share common parts

The EQ3-2 and CG4 are quite different from the smaller mounts - I have seen an Astromaster RA drive and theres no way it could fit on the EQ3-2 / CG4.
