NGC 7000, The North American Nebula



Wikipedia entry.

Photographed at X-Bar Ranch, between Eldorado and Sonora, Texas.

First time I've dealt with a "meridian flip." With a German Equatorial Mount, when an object passes from the eastern sky to the western sky, you have to turn the mount so that the scope switches sides. Getting the camera realigned close to where it was was a bit tricky, but not terribly hard.

Jupiter, 2 August 2010


First time around for this appearance of Jupiter, and I'm setting the bar high this year. We've had a high-pressure dome settle in on top of us the last couple of days, and the seeing has been, well, astronomical. I set up the gear before going to bed, then rolled out at 0500 this morning to shoot this. CSC said 4/5 seeing, and it may have been better.
