This mirror was made by Mr. R.F. Royce for myself at cost of $695.00. It was made about 6 months ago. It is a full thickness pyrex mirror, with a beral coating, which is in very good condition. The center is marked for collimating. This mirror is guaranteed by Mr. Royce to have a Strehl ratio of at least .96 and to be no less than 1/10th wave at the wavefront, 1/20th wave P/V on the surface, with no defects or ripple which would affect the mirror's performance. I will accept the best offer over $400, plus shipping. Payment may be money order, bank check, or Pay-Pal. Thanks for looking.
Best offer so far is $440.00. Thank You
