Using SharpCap's Polar Alignment feature
7 posts • Page 1 of 1
My question is about obtaining an "Excellant" PA via SharpCap. I have gotten pretty good at bringing the two parallel lines together and obtaining an excellent PA..............howerver....then when I start to guide via PHD2 and utilize the Guiding Assistant, the GA always informs me that the PA error is 5 arcmin or more sometimes. I don't understand it and it leaves me fairly confused as to what is correct.....PHD2 or SharpCap. Thanks for any help on this issue.
I just saw the losing Polar Alignment thread that talks about the same issue that I am having......I have not bumped the mount and everything is nice and tight, including the knob that holds the mount to the tripod. This issue happens every imaging session.
This past weekend I watched a YouTube video produced by PHD2 that talked about their polar alignment feature in great detail. The thing that struck me was their use of the term "cone error". I know what cone error is, and I know that Robin knows what it is. I would be shocked if SharpCap's Polar Alignment function did not account for cone error. So what I am suggesting is that PHD2's Guide Assistant is giving you a number that includes cone error.
