I've been dissatisfied with my Astronomik brand O-3 and S-2 filters because they are too broad (12nm) to provide adequate contrast. More specifically, if I adjust exposure and curves to match the…Continue
Hi,I recently acquired an AT111EDT. It is the older style with the R&P focuser. There is a "rotator" on the focuser that looks very good, but I find that when the knob is loosened the rotator…Continue
