Got back out last night and despite the he full moon managed to get some OK(ish) images of M31
Top is 26mins worth of mixed 8s 10s and 30s subs
Bottom is 72x10s subs with 10 darks and 10 bias.
All images taken with my 70d on my 250mm go-to dob, then stacked and stretched in SIRIL
Looks like I need to take some flats though - might try to take some today

Ok so I had another go at my M31 image
This time I re-stacked adding in some of the 15s subs to give a total of 8m20s!!
I have played around with curves and levels using gimp 2.9.5 and also tried adjusting the colour slightly - less red, more blue
I think it looks better, but the core is still blown out and the edges are now getting a lot of noise coming in - looks like I need more data (if only it would stop raining)

Thanks for all the tips and support. I'll have a go at processing again in GIMP 2.9 using curves rather than levels and see what I can get. Hopefully I'll get another clear night soon - I think I can probably push the mount to 15s subs if I get the tracking spot on, that plus more data should help.
Might also try some other targets - only really went for m31 as it was easy to get in frame using my finder
Thanks again
