Astrophotography

We lucked out with a moonless, no-haze, no smoke night sky yesterday.  I set up the little Ioptron Sky-Tracker and mounted my camera and 600mm lens, and commenced to focus/shoot/adjust/repeat.  Two hours later I had a couple of respectable images.  The first, M22, is a star cluster containing 70,000 or so stars.  The second is M8, or the Lagoon Nebula.  These are both 20 second guided 600mm single exposures.
