RA and DEC star alignments don't match
Posted: Wed Mar 14, 2018 6:48 pm
I love the PA tool but am bothered by an apparent discrepancy -- It could be me or my rig -- here goes:
I start with mount CW down, within 5 degrees of NCP - I fire up SC and start PA tool -- it plate solves immediately and requests that I move the mount 90 degrees in Dec - again plate solves immediately and I begin my RA and DEC adjustments -- I get it to say "Excellent" and am very happy-- I then rotate the mount back to CW down and the screen now says PA is "Good" instead of "Excellent" -- see attached -- is this normal or is there something wanky with my mount?
Regards,
Tom
