350mm f5 mirror


This mirror had a very poor figure when I purchased it from a well-known optical company and I was able to produce a big improvement with my first ever attempt to figure a mirror although it still has a fairly wide turned-edge and planetary detail is best seen with it masked to 320 mm (12.6 inches).

From the album:

350mm (13.8 in.) F5 home-made single-pole telescope
