New Look for Old Telescope

I 'm still mending a sprained MCL in my right knee so I'm still not really accomplishing much on my To-Do list.  Every now and then, however, I feel halfway decent and am able to jump into a small little project at the kitchen table.  This still needs to be short because I need to keep changing positions...  no sitting for a long period of time, no standing for a long period of time.  This keeps the size of these occasional projects on the very small side.  Plus, the longer I work on any project, the more likely I am to do something stupid with my knee.  The last thing I want at this point is to be set back to square one yet again.   I have this old Celestron 70mm refractor telescope that, in recent years, I adapted to a different type of mount.  In order to do that upgrade, I needed to remove a bunch of mounting hardware that was bolted through the optical tube.  This hardware wasn't needed and was in the way of the new mounting cradle rings and dovetail bar so most of the

This would happen over and over until the moon was too low in the sky.  My first
