Here's one you don't see everyday-Abell 53 (PK 40-0.1) in Aquila. Took this last night before the moon came up. Here in Minneapolis MN this time of year, twilght hangs on until about 10:30pm and with the moon rising about 11:30, it didn't leave much time to image. But, it seemed to turn out fine.
Here are the details-C11 @ f/12, MI-250, ST-8XME binned 2x2, AO8 correcting every 1 sec, 10x5 min subs, darks and flats applied. Only processed in CCDSoft using Add combine. Seeing conditions weren't too bad for a change. Outside temp was around 55 deg F.
If my info is correct, the central star is at around magnitude 20.
