Thanks Colin :-) I did do a reasonable amount of noise reduction on this one too, but I think it's fairly subtle when viewed at normal brightness. I often don't use much or any noise reduction on my luminance data, so combined with the longer integration this one is especially smooth.

Thanks Mike I thought I remembered you saying you didn't think much of this group once before... I just like three reasonable sized galaxies in the one field, but I really love all the background fuzzies.

Superb work.
haha thanks Mike :-) Have to say, cruising around this image reminded me of the hubble deep field; one of the images that got me into this whole game.

Thanks Suavi :-) I think that one might be a bit oversharpened, but eh... nothing's ever perfect

Thanks Peter :-) Yeah, my typical ~10hr images are looking pretty thin now...

Is this from a specific sharpening routine you use?

Just in case the motivation of this post is misinterpreted, may I emphasis that I am not doing a form of infamous roll-over style attempt at discrediting here , I'm just curious, it looks incredible

Mike
haha, can't get anything past you, Mike! Good pick up. I'm trialing out some AI software for both sharpening and noise reduction.

For sharpening on this image I did a very mild deconvolution on everything but the stars. From there I used AI sharpening which I applied to only the three main galaxies; I masked out everything else. I applied more on NGC 7582 than I did on NGC 7590 and NGC 7599, because 7582 had a kind of chunky look to the detail that I didn't like and that went away with more sharpening at the expense of some artefacts... which I prefer, but acknowledge isn't perfect

The noise reduction I used I turned right down to the lowest setting and even that was too strong. I ended up blending it back into the image at 60% opacity.
