It’s a big 12.5 inch Telescope! Yay!

Wow, this is quite a find. A friend lucked into a long term loan of a telescope. It is a 12.5 inch Meade Dobsonian. It is probably around ten years old and it has stood vertical with no cover for quite a while so the mirror needs work. We are going to have a lot of fun with this enormous light bucket.

The first order of work was a bit of cosmetic cleaning. Secondly we removed that mirror and tried to clean it. But that is a no-go. So…. it looks like we are going to have to send this thing out to get re-mirrored. Oh well!









The mirror is in pretty bad shape:








We tried cleaning it but the contamination has eaten through the aluminum coating. Drats! WEll, we technically still can use it. It just won’t be at maximum efficiency. I will keep you posted on this project!
