Description

Well, sometimes a lot of things went wrong on the same time. The images of NGC 7023 are a good example for this. The flat fields are not matching (possible to bright). Blue frames were taken when it was not really dark at all. Green images are okay, but together wit the blue ones they show heavy noise. In the half of the red images I had to rotate the camera to avoid collisions (don't work with three rotated red frames)...

... and here is the result. I apologise for the dark donuts and the absence of the cool dust structures. I will do this object again.
