Old data thru eight inch F5 Nikon D5500 about an hour of 30 second subs 1600 iso unguided HEQ5 mount dark location
.
I have been trying to learn star tools going thru old data and this is my result..after Startools I gave it a level change in GIMP and cropped to help with downsizing...it was probably a little better a few twiddles earlier

This I would like to see how it turns out here and to show what 30 seconds can do.
Not sure about the colour as it is when colour blind but I adjusted colour on the basis of what detail seemed to pop out...
