Comet Garradd Hyperstar III night of 25/02/2012

Beautiful clear evening all night last night but I packed up at 2:30 in the morning after starting at 7:45 p.m. the evening before.  This time the target was comet Garradd moving below Ursa Major and above Draco.  I wasted half an hour finding it by eye instead of taking the co-ordinates out with me, and then I wasted another hour of good imaging time by dithering the data which causes me to lose 45-seconds between each sub.  I guess I still have a lot to learn 🙂  Anyway here is a very quick and very nasty process of last night’s data – a lot more could be done with it and I’m sure I’ll go over it again and again in the next few weeks.  I think next time I will autoguide on the comet itself and let the stars trail – I might also cut down to 3-minute subs which should be sufficient.
