Ad Astra Observatory

I bought a 13.1” f/4.5 mirror and matched 3.1” secondary today for $400.

It used to be a Coulter red-tube Dob, but I’m just getting the mirrors.

They will turn into the optics of what I hope will be an insanely fast 1500mm f/4.5 astrograph. I’ll have to spend a lot of effort to keep the scope light enough to be carried by the G-11. But I’m really excited to see if I can get it to work.

Wow. A 13” scope.
