Description

This was the best I could do without any decent equipment, and is actually the first legitimate image I've produced with the Sky Watcher Star Adventurer. I used my 10+ year old Canon T3i, and a cheap F1.8 Canon 50mm lens which had massive amounts of distortion generating all kinds of star issues. I've tried to reverse the distortion as much as possible, but you can still see it. The original image looked pretty terrible. The Star Adventurer was the champion here, absolutely perfect tracking, alas, there was no dithering and the old Canon puts out enough noise that you can see it in the final image as streaks.

Thanks to the super fast lens, this was just shy of 1 hour of data, and the camera battery died. No flats, darks, or bias images. I'm traveling and the skies here are bortle 2 class.
