0.98 Strehl! This a Chinese made mirror. The coating is in decent condition (not perfect, but completely ready to use); no nicks or thin spots. The figure is very good. (The spots in the first photo are reflections of nail heads in the wall board.)

As evident in the photos, this is a thin mirror, about 1".

I tried building this mirror into a highly portable dob as in Gary Seronik's article about another of my dobs (see Sky and Telescope, July 2015), but at f4.7 the focal length was a bit too long. If you are keen, the "drum shell" mirror box with mirror cell and front collimation adjustments is also available.

Shipping costs need to be discussed.

Thanks for looking. -- Michael
