About this image

M81 Bodes Galaxy, in constellation Ursa Major, 12 Million light years away, with a diameter of 90,000 light years.

Data captured over 2 nights, 22nd & 23rd Nov 2020
This is a re-processing of data captured many months ago – have learnt some new progressing techniques so wanted to edit the data. Plus, the weather has been terrible for ages so I want to keep “up” with progressing techniques.
I think over the year I have continued to increased my knowledge of processing techniques or should I say, scratched the surface of the techniques a bit more :)
I posted my original work here in Nov2020

 

Photons captured in my garden, Bortle 4.

 

Processing; Deep sky stacker, Pixinsight with final tweaks in Photoshop + Topaz DeNoise AI.

 

Clear skies all.
