CG-5 Mount and Polar Alignment Scope

Yes, I understand that the Go-To mount alignment should be good enough but I'm curious none the less about this situation on the CG-5GT mount.

FWIW, try reading the manual.

I think you need to remove the ring from the CG5 with the 3 set screws, and then the new scope screws into the back. The ring with 3 set screws was used for an older style polar scope (like on mine). I hope this helps.
This makes sense. Searching with Google revealed there is an older polar scope with a part number of 94221 that appears to be difficult to find. It also appears that you really just need to rough in the polar alignment and then finish up with the Go-To two star alignment. There also seems to be some recommendations for getting a reticle eyepiece with cross hairs for the 9.25 SCT itself to make sure you center the alignment stars in the telescope field of view.
Thanks everyone for the help. I've been interested in amateur astronomy since my teenage years, had a small, inexpensive Tasco refractor that I fumbled around with. I recently retired from AT&T after 34 years and my family gave this fine setup for a retirement gift!
I live near St. Louis, MO and there is a local club called Riverbend Astronomy Club that I have contacted and will try to make some meetings.
