M81 & 82

Processed data acquired from March. 1hr integration with Canon 550d + CLS filter & SW250Quattro, not started guiding/dithering a year ago but had the polemaster for bang on polar alignment, so it wasn’t too bad for 12x5min subs

Very useful masks made utilising Starnet++ in PixInsight, which helped isolating stars and structures for more aggressive background noise reduction to clean up the noisy canon550d at iso3200.

This pair are always a difficult, the background would benefit from SCNR as it is very green, a good mask and a background desaturation would make a big difference. Very nice otherwise.

Thanks I didn’t notice the green until you say so, I think my pc monitor has a slight different tonne to my iPad screen.

Nicely detailed galaxies showing the benefit of a fast, big aperture scope.  Great job.
