Swan Nebula M17

This was taken in alt/az mode with NO Guiding it is amazing the detail you can get from 25sec subs.

I have just started to use Startools for processing I am impressed with it so far.

nice one Wayne. 500 subs - wow! My pc was would have no chance of stacking that many subs in one go.

WOW !, It’s a very nice result.

Some brighter stars have N-W tail, I think is because of Alt-Az.
Maybe you can go through all (500) frames, find those most affected and restack the lot without them.
