Williams Optics 66mm Zenithstar Doublet Refractor with X0.8 Flattener
Since I got my bigger setup this little guy is no longer being used so it time for it to go. I mostly used it as my guide scope and as a grab and go.
I star checked it last night and it’s a very well corrected doublet as you would expect from William Optic’s. I believe it was built in 2007.
