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

Thanks for the compliments and advice Martin and that's a great image of NGC 1365 from bortle 8 skies by the way. In this case I was just interested in the image scale on a 100/550mm telescope using the 120MMS sensor. I realise I needed many more subs to make these look more attractive but on this occasion that wasn't my goal, it actually wasn't a very good night to be out taking shots at all - windy and rather warm. The experiment achieved its purpose in showing how these objects will frame.

Thanks Peter, it's a start if I want to take this any further than wondering how these objects would fit in the frame using this set up.
