Excellent work. In the eyes of this relative newbie, your noise reduction seems a touch too high. But I'm not picking. Well done. Thanks for sharing with us.

Owing to the bright sky here at almost 54°N the background was pretty noisy though I thought that I'd only applied a moderate level of noise reduction using NXT.

How lucky am I? My image was used by ITV News in an article describing research by Dr Joanne Pledger, an astrophysicist at the University of Central Lancashire.

The local society (PADAS) that I'm a member of has strong links with UCLan through use of the Jeremiah Horrocks Observatory on Moor Park in Preston and public outreach activities.

Just a download from a Facebook post I made, so not the best quality, but still cool 😁

Animation showing appearance of SN2023ixf in galaxy M101 last month using two images, first captured in March-April 2018 and then with the supernova on 21st May 2023 (image in original post here).

2018 image captured using a 6" refractor and 'old school' mono-CCD with LRGB filters over 4 nights, with 2023 image using a 6" RC and OSC CMOS camera.

Colour balancing between the two isn't perfect but the result isn't so bad IMHO...
