Fast newtonian has this "bad name" for the difficulty of collimating them ... completely true! but at last we succeeded in having good star shapes and we started to using it again!
First result:
Dumbbell nebula is quite easy to image, it is bright, and thanks to the fast optics we were able to obtain a decent image in just one night in spite of the high light pollution.
Stacked with DSS, post processing with Startools
