Various thoughts and activities related to my amateur astronomy interests including telescope making and observing. Plus other stuff that may be on my mind.

8" Ballscope Refinished
The 8" Ballscope is now refinished and she looks great! I got the opportunity to use it at Perkins this past weekend and she did pretty good. However, I discovered something interesting: she bounces like the 12.5" scope now. About 5 seconds to dampen vibrations. The 8" scope never did this before. One of the things that I did differently in this scope was use the threaded rods to separate the mirror cell and the lower compression ring like on the 12.5" I used wooden dowels before on the 8". This week I will be cutting some 1x2 solid oak pieces and wedging them in there to see if that makes a difference. I will cross my fingers!
