Brand new 200mm (not the advertised eight inches)200mm primary mirror from a eight inch Sky Mentor . I removed the mirror from the scope and replaced it with a full size 8 inch f/6 mirror.
I only purchased the scope to mount the full thickness mirror I already had as it was of excellent figure. Turns out it was a lot less expensive to do it this way than build an entire scope. At any rate I have a brand new mirror of known quality for sale. The GS mirrors enjoy a good reputation. A Royce it is not but it is definetly a good quality mirror.
