Faint southern spiral galaxy IC5332

[gregbradley]

I did this one a while ago and was never quite happy with the processing.

I have reprocessed the image from the ground up and there is still a bit of noise that only mega hours would fix.

Perhaps a project next time it is up with more aperture and I can add that to it.

But as it stands by itself now I am much happier with this result.

Keeping it in perspective this is a really faint galaxy.

It's certainly not an easy one Greg but your version looks pretty good to me.

Cheers

[Stonius (Markus)]

Nice! I really like that you've captured many other fainter galaxies besides, particularly the strange one at 2 o'clock.

[Shiraz (Ray)]

nice work Greg, especially with such a dim object - well done to extract that much detail.

[RickS (Rick)]

Nice repro, Greg. It reminds me a little in structure and dimness of NGC7424.

[Rex]

Nice one Greg. Lots of detail showing.

Thanks Steve. I had some good seeing and there was some nice data in the captures.

Thanks Markus. Yes that is a strangely shaped galaxy.

Thanks Ray.
Its one of the last from the SX694 series as I have changed direction but still have several to process and publish. I've enjoyed the 694 camera but always wanted to optimise the CCD to the Honders. Your spreadsheet also brought home the importance of that.

Cheers Rick. Its amazing what modern gear picks up.

Thanks Rick. Oh yes, 7424. I tried that one once and it was quote a weak image for me. Probably a dark site large aperture target.

Nice work on such a super faint galaxy Greg.
cartes Du Ciel states the surface brightness as 14.5

[Paul Haese]

I think this looks better Greg. The previous one was a bit black point clipped. I think doing this image with the CDK17 and the larger sensor would work well.

Agreed!

At the risk of getting shot, I suspect I'd most like to see a version about half-way between the new and the old: setting the zero point where there's no important clipping of the blacks, but still very contrasty.

Very nice work in either case.

Thanks for that.

Yes it would be better with the CDK Perhaps another go at it later on when its up again.

Background is a tad bright still. I did already pull it back a tad. Perhaps not enough.

I like it... I like it a lot.
Nice little seashell type galaxy in there as well,
I wish more people would go after obscure stuff like this.

fwiw) The catalogue number threw me for a second.
My brain registered NGC 1232, which has an almost identical morphology.

Incidentally, the first link has the camera down as the proline, the crop as the trius... not sure whether that is a typo or not?

nice work Greg, very faint indeed - but worth it for sure.

Cheers

Very cool field Greg. Very interesting features in that galaxy and lots going on around it as well. Nice one.

Thanks Clive. I fixed the listing of the camera used.

Thanks Russ. Also it was taken with some pretty good seeing so the data was very tight.

Thanks Marc. There are lots of galaxies to image the problem being most are too dim or too small.
