My first go at NGC 2683 - UFO Galaxy. It was a bit of an adventure capturing this one, though it was a secondary target behind NGC 1333 to round out the night of imaging. I’m still working on processing NGC 1333 (the dust has been a real challenge - and I think I need to retake flats.) I also had essentially two nights wasted, as I set everything up and got it running, but the rig shut down mid-meridian flip both nights. I later decided to watch the flip and discovered that, with this particular target for whatever reason, the power cable rotated slightly in the ASIAir upon meridian flip and this was enough to turn off the ASIAir mid-meridian flip (not ideal!) Unfortunately this means that I missed out on about 5 extra hours of integration time on this target (and about 10 hours on NGC 1333!), but I decided enough was enough and it was time to move on to another target. I also needed to toss perhaps half of the other subframes I collected due to some interloping clouds.
