NGC 7424: the lost spiral galaxy

[Shiraz (Ray)]

outstanding effort Rick - that is only mag24 surface brightness isn't it? To get such detail and colour on something that dim is exceptional. Regards Ray

Thanks, Andrew. That's certainly a vote of confidence!

Thanks, Ray. It is very dim but I wasn't able to find a definitive surface brightness.

Beautiful galaxy. Great image, lots of great colours. Nicely done

Thanks,
Rick.

Sorry Rick - I think I must need new glasses. Whatever galaxy it is it's a very nice image.

FWIW, DSO browser lists it at 24.18. regards Ray

No probs, Steve Thanks for the comments.

I hadn't seen DSO browser before. A very nice resource. Thanks, Ray!

That fair pops out of the screen, all aspects of processing look very well done, balanced . And a lot of data, shows.

[Rod771 (Rod)]

Very nice Rick

Well done

[Spookyer (Brett)]

Hi Rick, so that is what you were targeting, great work on a tough target.

Thanks for the help and advice at Astrofest! Hope to meet up again sometime.

cheers
Brett

thought the photons were missing near us at astrofest - fantastic colours and details of the arms - absolutely a visual treat

Yes, that was what the poor little scope was chasing every night until dawn It was nice to meet you too, Brett. See you at AF next year if we don't catch up beforehand!

Thanks very much, H0ughy! I had to keep my scope well away from that Hyperstar set up. There wasn't enough photons for both of them

Stunning result Rick, 3 nights dedicated to one Image, wow, Im flat out doing 3hrs
Very creditable stuff

According to the LEDA galaxy catalogue NGC 7424 has a fairly dim surface brightness of 23.395 mag/square arc sec compared to NGC 6744 in Pavo at a slightly brighter 22.680 mag/square arc sec

Thanks for the numbers, Mike. That means that NGC 6744 is nearly twice as bright as NGC 7424 (1.932 times brighter). Having imaged both I can easily believe that. NGC 6744 was a doddle by comparison

[prokyon (Werner Probst)]

Great result! You captured so many details in that small galaxy.

Thanks, Bob! I'm over the initial phase of chasing 5 objects in one night and trying for better quality. It's hard work though

Wow, mag 24... that's a sky-background limited exposure even under those dark skies. Faint indeed!

I'm glad I didn't know that beforehand

[ChrisM]

Great result Rick, and worthy of your effort.

A top shelf image, Rick! Beautifully presented. The quantity of data has really paid off no doubt. Sure, we always want more but I suspect you've hit the point of diminishing returns with is target. Well done.
