Alternative Polar Scope and Drives for GP2?

[ironeyes]

Hello all,

Long time lurker first time poster.

Have had my OO150 scope on a Vixen GP2 for a number of years and would like to try my hand at some imaging.

Does anyone know if the Skywatcher EQ5 or Celestron CG5 polar scopes fit the mount?

I have asked a number of retailers and they suggested asking here before making a prospective purchase.

Similarly can alternative brand drives be fitted to the GP2?

Unfortunately the Vixen polar scopes and drives are really expensive - yeah, you live and learn!

Any info or advice gratefully received.

Best wishes

Nick
