On the opposite, a shallow mirror (e.g. F/D = 8) will be performing very well on planets and the moon. The theory behind grinding is that you can remove glass as long as you use a material with a higher hardness. Telescope makers use silicon carbide powders (a.k.a. carborundum) for this task. It is cheap and comes in various size (can range

The Starfire project provided much of the funding for a new polishing lab built in 1990 and equipped with an 8 m grinding and polishing machine and a 24 m test tower, which were first used to figure the 3.5 m mirrors. The Mirror Lab was not free to choose the focal ratios, so these mirrors were more conservative at f/1.5 – f/1.75

GRINDING A TELESCOPE REFLECTOR WITH TOOL

Grinding telescope reflectors of 15-inch diameter and over makes it necessary to employ a motor-driven turntable. Small mirrors are generally ground and polished by rotating the tool, fastened to the turntable, and working the mirror blank by hand either in straight or in circular strokes over the tool. In this case the overhang of the mirror

Mar 06, 2006 Gordon will know more about the math for different mirrors and different sizes. I recall for mine it was about a 70% tool diameter. The bucket Gordon used to make the tile tool was 8 15/16 , 70% of 12.5 ends up at 8 3/4 . Looking back at my notes I used the tile tool primarily at the 70% zone of the mirror
