This galaxy is described as a chaotic spiral and is a member of the Sculptor group. It was imaged over 5 nights under generally poor conditions (intermittent clouds and mostly bad seeing.) I would have liked more data and the luxury of dumping some of the weaker subs but the weather didn't allow it this year.
I do particularly like the assortment of small fuzzies in the background. There's also a pink spot on the outskirts of the galaxy at about 5 o'clock which is apparently a microquasar composed of a normal star and a stellar-sized black hole.
Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: 19x1200s L, 8x900s R, 7x900s G, 9x900s B
Beautiful field, lovingly processed Rick. Its such a pleasure to swim around the big field of the U16 at that res. I shudder to think it could be any better if you had encountered better conditions.
Will have to head off the books. Not familiar with this one, but congrats on the outcome.
Yeah looks like the seeing has affected it slightly but still a great shot, living in average Oz and not the Chilean Andes we can't only image when the seeing cooperates, poor seeing doesn't invalidate an image, lots to like here, the colour and brightness are great
A wonderful, deep shot, Rick. I had in ignorance thought of this galaxy as a "semi-dwarf", and therefore perhaps rather irregular, but you've shown that there's lots of beautifully photogenic regular structure, reminiscent of NGC 300 for example. You've also captured a great deal of form and colour in the little fellows in the background. Yum.
Nice shot Rick,
I think it would look better if you adjusted the contrast using curves
of just the bright part of the galaxy - using a blurred mask.
I'll post an example if you want?

And thanks, Erik!

Thanks, Mike. It didn't turn out badly but I know the gear (and even my processing) is capable of better. That's life

Thanks, Geoff.

I've tried quite a lot of different ideas on this one, Allan. If you have any suggestions feel free to give it a go.

Here is a go with your small pic:
Contrast with feathered blurred mask on galaxy
LAB to give more yellow at center of galaxy using feathered mask
1 pixel sharpening with mask at center feathered.
(only 5 minutes work )
Nice to look at and a very respectable result for 0.67"/pix in poor seeing Rick!! Very pretty field with lots to look at too. I too would try to add some more contrast into the galaxy to bring out the structure - probably using proper unsharp masking (i.e. not the PS filter) & curves.
This is a beautiful shot Rick. How many spiral arms has that thing got????? Imagine being on a planet in that bad boy and looking at the night sky and seeing the spiral arms above. Love the background fuzzies as well. Really nice galaxy, I have resolution envy lol.
Very nice Ric...looks like you were looking for a halo me think.
Thanks, Louie. I'm a sucker for a halo

Is this better?

Looks better at that small scale, Allan. I've done a bit of a tweak myself. See below...

It's an odd one, Rex. Thanks for the kind comments.

Thanks, Steve. I usually go a bit over the top. I thought yours was very nice but conservatively processed.

I like that Ceravolo of yours!

Thanks for the feedback, Marcus. I did a bit of wavelet hokey-pokey. Is this something like what you had in mind?
