Removed the 6” refractor from the main scope and returned it to Bob. Removed the old finder scopes from the orange Celestron, installed and aligned a Telrad finder. Added some duct tape to the inside rim of the dust cap to ensure the cap fits snugly when in place. The new Celestron mounting plate is not compatible with the existing Vixen style base plate on the 24” scope. Removed the base plate and gave it to Blair so a wider plate can be fabricated. The existing side rails can be reused.

I looked at the black-tube Celestron, collimation was definitely out. Focused on the small lettering on a coffee can and there were at least two misaligned ghost texts appearing. I did manage to get a coarse collimation done to eliminate the ghost text issue. No stars were visible to check the diffraction ring alignment.
