M4 and Antares

The sky was completely free of clouds all day so Bob and I decided to go up into the Valles Caldera and take some astrophotos. I piggybacked my new 300mm lens on his telescope and this was the best shot we managed:

The focus isn't perfect (I had autofocused on the half moon just before it set and then attempted to not touch the focus ring while mounting the camera), but it's reasonable. The Antares nebula shows up well. I'll have to look at my charts to see what some of this other stuff is.

I'm pretty sure the green UFO is a camera artifact. Something similar appeared just above Rigel in my Orion shot. Anyway, a great night for stargazing. Transparancy was relatively poor and the seeing was pretty bad, but no clouds, not much wind, and the temperature was agreeable.
