Horsehead and The Flame Nebula
20:52 27/12/2008 UTC
It's been a long time since I was imaging last time. We have had a long cloudy period and whenever there was clear sky, I was occupied somewhere else. During the christmas holidays I had an opportunity catch some photons and test my MT-1 motors for the mount. Everyting went quite fine, sky wasn't totally clear however. But still I was able to capture something about this nice target. I also begun to build a library of carefully prepared darks, this time I used one made in -5°C from 40 frames. Should be somewhat free of randon noise...
