Description

So well, there was the full moon rising above the horizon, so no good time to take images of deep sky objects...but as is was one of those few clear nights in the last time I just had to give it a try! I used a modified Canon D1000 but with no filters at all. As a result the lightpullution in my pics was really bad and i was really struggeling in postprocessing with this huge gradients and color noise!
