This has been on my list for a while, but I haven't managed to get any significant amount of data on it until this year.
Had some clear nights forecast this week where I set up and the seeing was amazing only for my rain alarm to trigger, leading me to pack up before I even started imaging. Still, I ended up with a couple of good nights for luminance, the integration coming in at roughly 2.0" so I can't complain too much. Colour data was reserved for the junk nights, FWHM in excess of 5" on some of those.
Had hoped for another night tonight but the forecast has changed so it's looking like a no-go.
Not sure I'm happy with the processing yet, but I'm sure I'll receive some useful feedback here before long and find myself redoing it a thousand times ;-)

Gee Lee...that's a really excellent 1097, detail and colour are super Loved looking around the image, a real galaxy lovers delight You are becoming the galaxy king
Hi Lee,
that's an excellent picture.
I like the way you've kept the noise in the background -
it let's us see where the noise floor was.
The colours are great and the detail is superb.
That's nice Lee. The jets are well seen and colour is excellent. Detail also superb.
Thanks Paul :-) Yeah, I don't usually push my images very hard in terms of faint detail, I've never been too successful with that, others have brought out the jets a lot better. I'm just happy you can see them at all.

Mike
haha, thanks Mike. I don't know about the galaxy king, but I sure do like 'em. So much so that I've sold off my NB filters and will now focus pretty much exclusively on galaxies.

Thanks very much, Mike Have you guys done a colour image of this one? I found some very nice L data of yours, showing off those jets a lot better than I have, but no colour. Would love to see you guys show us how it's really done.

Thanks very much Allan :-) I actually did quite a bit of noise reduction on this, but it led to a lot of artefacts so I diluted it significantly by blending it back with the original. I'd prefer less noise and that's something I may revisit.
That's a super 1097 Lee. Fabulous colour and terrific core detail.
Greg.
Thanks Greg

Maybe a touch heavy on the deconv for my tastes, but I’m weird
Cheers Dunk! There wasn't much decon on this one, but maybe it's the combo of decon, MMT and AI sharpening that you're not feelin'. I tried to do just a little of each
Thanks Greg

My decon meter is pretty damn sensitive and it hardly quivered, nor did my very recently acquired (courtesy of you) AI/loopy sharpening meter
Lovely detail all the way to the core on your top pick pic
Thanks Chris!

MMT is MultiscaleMedianTransform which is a general purpose wavelet-based tool in PixInsight. Two of the main things it's used for are sharpening and noise reduction.
Using MMT you can basically increase/decrease the "weight" of different scale features in an image, which effectively enables a kind of ringing-free sharpening if you increase certain (typically small) scale structures. It's also good for noise reduction. It's really easy to overdo it with MMT though so you gotta be careful with it.
I use MMT quite a lot, including for minimizing the impact of dust donuts if I don't have flats and even for extracting large scale structures which make for better modelling when removing gradients.

If it didn’t send Mike loopy, you’re on solid ground

Sorry...been a bit busy of late and missed this one.
Narrow field with that sort of intrinsic resolution is no easy task.
It's so refreshing to see someone make their instruments sing, rather than plug and play muzak.
What a cracker of an image....my only complaint would be... I'd wish I taken it
Thanks very much, Peter :-)

What AI sharpening are you using?
haha. Yeah, I thought I was safe when Mike didn't comment on it :p
I'm using Topaz for both sharpening and noise reduction. Honestly I don't think it did a great job of sharpening on this image, I think it might be too oversampled to work well with Topaz. I only used it sparingly because it was more artefact than sharpening on this one.
