CCD Polar Alignment
Firmly in the “one picture is worth a thousand words” category, this is a quick, easy, and accurate method of performing a polar alignment on a telescope mount. No red crosshairs, no […]
Pointing model building
I have noticed that I have to run multiple iterations of Polar Axis Correction to get it right. Last time out, I had to run it about 3 or 4 times, plus […]
