Here's another open cluster I did last night when the moon set. 2.5 hours on IC 4665 in Ophiuchus. The exposures are all 300 seconds unguided. This is a nice open cluster with about 30 blue stars and is pretty close to Earth, 1400 light years. It's 36 million years old and is approaching us at 12 km/sec.
