Mick,
Great effort on difficult targets under light polluted skies
Well done !!
Galaxies under these conditions can be successfully imaged with shorter focal lengths and smaller aperture scopes, you just need to image during new moon period , if using a OSC camera just an IR / cut filter or luminance filter and heaps and heaps of short subs
Here my image of NGC 1365 great barred spiral galaxy ( magnitude 9 ) from last year under Bortle 8 Sydney suburban skies and Neigbours lights blasting my yard using my 6” newt and 2600MC which just has a IR / UV protective window ( I used no other filter)
180 x 50 sec subs plus 20 darks
Stacked in DSS
Processed in Startools
Your images are a great start , keep at it , just more data is needed
Cheers
Martin
