older Nexstar C11 GPS OTA disassembly

Recommended Posts


Just got a CGX GEM, and want to put the C11 on the new mount.

Got the OTA removed from the fork assembly.  Optics need cleaning, but having trouble removing the corrector plate.

The retaining ring would not come off.  It is almost like it had some glue and a thin gasket on it.  Is this normal?

With difficulty, it came off without damage.  But, now the corrector plate seems to be glued as well.  Same sort of thin

gasket visible to me.

I am going to remove the other end where the main mirror is, then try and push the corrector plate from the other side while

pulling from the front.  Does this sound feasible?

Take care,


Moultrie, GA
