Sigh, it never ends... On my never ending quest to get my friend up and running, after getting the autofocuser working we tried 2min exposures on the rosette nebula hoping for success but only to see that we still have some sort of tracking issue. The setup: Astrophysics 6 inch refractor F-9 focal length AP 1200 mount SBIG 402 ME camera DF-2 focuser SG -4 autoguider AP 1200 was set to sideral time with the hand control, we did not use periodic error correction. We used the astrophysics right angle polar alignment scope, checking the position of polaris at 8 and then 5 hours later and it seemed to be the correct location according to the astrophysics iphone app. I've attached a representative FITS files, the rosette nebula is without autoguiding and the ngc 2903 image is with autoguiding. The "streaks" seems to be in conjugate directions. Does anyone have a good guess as to what might be wrong? It doesn't feel like polar alignment since the alignment appears to be good and I think the relatively modest exposure times (2min) are long enough to worry about PEC on this mount. But I have no other guesses after that. Would love any advice that any of you have. P.S. I've also attached two autoguider log files (it isn't clear to me why they appear to be in different formats...this is something to do with how my friend captured them) in case that makes anything obvious.
