Example of CGEM tracking/guiding capabilities. 2+4 sky alignment. "Display Align" showed -3 degrees off in Azm and + 30 min off in Alt. A single attempt at All-Star Polar alignment using a star near the meridian/celestial equator intersection, resulted in excellent guiding. Hypertuned CGEM, Starlight OAG w/ AO and Lodestar on FSQ-85 @ f/5.3 NOTE the Y-Axis scale(0.5 pixels per div) and RMS(0.08/0.1 RA/DEC). (also shows quick V-curve and gotofocus using scopefocus autofocus software)  Older similar example: 20 min. sub, Pre-hyertuned, PHD guiding w/ SSAG on modified finderscope. 20 minute exposure  FSQ-85 and TSA-120 on a CGEM with servo driven EL Flat panels.  FSQ-85 w/ QHY8 & TSA-120 w/ ST-8300m, Home Modified filterwheel, OAG, Lodestar and Reducer  New geared stepper - nema 17 w/ 71:1 planetary gear box   Motor mounted to FSQ-85, uses Robofocus plate and coupling  Motor mount on TSA-120  Flexible Coupling  Mount under finder bracket  |
