Re: AP600 vs Mach 1


I ran some tests on terrestrial objects today. With the tripod feet firmly in the ground, and everything tight, the 35lb 6”f9 OTA, when rapped firmly on the focuser, showed about a 0.8 arcminute vibration that dampened in 3.5 seconds. The flexure seems to mostly be in the hardwood tripod.
