M29 - an Open Cluster in Cygnus
Taken on 23.7.10, a poor night of mixed cloud and clear, with lots of thin hidden cloud and haze, which shows itself as a streaky background. I'd done some collimation on the Vixen and needed a test and this was near where the mount was pointing at the time, the middle of Cygnus. I didn't have time to get the guide system into operation for fear of cloud attack so ran 30 frames at 60sec. No flats, which would have helped the background.
Sometimes called the Cooling Tower cluster, it's not particularly inspiring, quite small too, 10 arcmin and mag 6.6, so should suit the Meade's 3500mm FL, with a big enough chip. The Vixen's is 3000mm. 30 mins is what this took, and that should be plenty for most clusters, and Cygnus is full of them.
