Thanks for posting these and starting this thread.
I wish there were more mirrorless ILC cameras talked about here. As you probably recall, I recently picked up a GF3 because it was cheap and I could use my old lenses on it.
But it can only shoot up to 1 minute, and higher ISOs than about 800 or so really pull a good vacuum. At the time I took this shot, I didn't have a decent camera mount, so I used a 1/4"-20 threaded rod and a couple of nuts to hold it on my scope's saddle. So, while I was fiddling with other stuff, I shot this 1 minute shot of some random sky toward the center of the Milky Way. I really like the stars with this Konica 135mm lens:
Now, I'm at our dark Utah site again for a few nights (though it might rain!). This time I have a couple really nice ball mounts for attaching the camera to the scope saddle and aiming.
