Captured 8th Sept 2021 just after midnight.
Celestron AVX mount, Vixen 81s refractor, Altair 183C. Unguided, focus with Bahtinov Mask. SC 4.
Camera Settings: exposure=60s, gain=300, black level=30.
Lights 100x60s, darks 50, flats 50, bias 50. Astro Pixel Processor stack best 80 of 100, GIMP, Neat Image for mild denoise.
I managed to retain (not destroy during processing) the stars near the central core, so am happy with that. Just need some weather now to capture another ~200 frames.

Nice one Dave. Central stars are indeed there.
M31 always is a balancing act, especially with slower telescopes.

Thanks Menno. M31 is well placed for me this month. I want to try to push up my integration times. I have an Altair 183M that I could use to add some Ha frames as well.
Same camera, 3 years ago, some improvement:

Hi Dave,
That is a massive improvement over the earlier one! Nice detailed image and colour. Weather seems to have been more of a problem this year than usual.

Thanks Tim. I am keen to add another 2 sets of 100 frames to see the effect. This was captured at home (North East of Manchester) under Bortle 6 skies.

3 years ago my main processing skills were:
- over stretch (because of poor data) and destroy colour
- introduce large amounts of noise

The Altair 183C has an internal fan which can be OFF/SLOW/FULL. It is not TEC cooled. The images were captured with the fan running at FULL speed.Do you have the data of the cooling, or is the camera air-cooled
