Description

M74. This is the third time I've tried with this object, and still struggling with it, so I combined the subs from the last two attempts and now looks more like a galaxy!

Second attempt with atrous smoothing rather than TGBDenoise. Also applied a little HDRwavelets to bring out the colours better in the core.

As per Callum's request, I've combined the first image with HDRWavelets as image C (also uploaded version B again, this time with the same orientation to make comparisons easier)!

FInal version, I think before I integrate the Ha data. For this version, I applied am inverse Lum mask to TGVDenoise, and also reduced the mask I use for HDRwavelets by 2 so that it brings out the details, but is not as harsh. Not sure I can reduce the brightness of the background any more without losing the extended spiral arms.

Thank you to everyone who has commented - this is a much better image as a result!

Finally, also added Ha data to the image.
