Quote:I'm looking over procedures and had a question. When aligning Polaris through a polar scope, I've read to adjust the tripod legs, but wouldn't this throw off the leveling? Does that matter? I've always adjusted using the elevation knob, but that sometimes takes me off my latitude mark by a few degrees. Which is the proper way to do it?

Quote:I found that you don't have to power cycle the mount after ASPA. What happens (at least on my CGEMDX) is that the calibration stars are cleared after ASPA. Re-entering them allows me to measure the introduced error after ASPA. This saves a little bit of time in the alignment procedure.

Quote:After doing 2+4 and then ASPA I checked with PEMPRO and it registered as less than 2 arc minutes on both axis. After fiddling with it I was able to get it down to about .6I find that to be really really good.
