ic65 (gamma-Cass) in Ha

[ChrisLX200]

Testing my new mount last night, conditions were not great but hey - at least there were stars to be seen! I was more interested if I could get usable 30min subs but my PA was not quite good enough (12 arcmin off) which I though wouldn't matter when using dual-axis tracking, but apparently not and field rotation shows. I made the necessary adjustment at the end of the session (1.3 turns of the AZ knob) and will check next time out.

I have no idea, I went back to look at the raw data and it's actually on 4 of them (not all 5). I guess it must be a reflection of some sort?
