NGC253 - the Sculptor Galaxy

[ozstronomer (Geoff)]

Great Repo Rick, plenty of detail in the core, processing looks spot on..

I really like this one

Thanks, Allan. I don't know that the Ha made as big a difference as the improved processing chops
but the old version is here: www.iceinspace.com.au/forum/showthread.php?t=112010


Hi Rick,

The Ha & the processing have made a significant improvement.
I will use Ha on my next attempt at this galaxy.

cheers
Allan

Amaizing proccessing and the rest of it

Thanks Pete & Bob!

Nice!

Thanks, Andrew. Jay GaBany did a version which appears to show stuff sticking up out of the plane of the galaxy everywhere. I still can't decide if it is real or illusory.

You've raised the bar even higher with that result.

Thanks, Andy.

By the way, we're all subs 1x1?

All subs binned x1, thanks Steve.

Look forward to seeing it, Allan!

What a stunner Rick!

The large version is spectacular to look at!
Wow a lot of time on HA! Must be hard to bring out these regions.

Cheers,

Justin.

The galaxy detail is top notch, but the faint background stars look a little weird.

[Marios (Marios)]

Inspirational mate well done..

Thanks, Justin. At that image scale with an object that's not particularly bright in Ha a lot of exposure time is needed to get the noise down.

Thanks, John. I noticed that but struggled to do anything about it. Sacrificing the halo did the trick but I wanted to keep it. Something I'll have to work on in future...

Amazing clarity and definition Rick. Nicely processed.

Peter

[RickS (Rick)]

Thanks, Peter! You've been quiet for a while. Hope you've been imaging and processing

[Peter Ward]

Dynamic range a bit so-so (a bit more light and shadow would make this a killer image)

But sublime res.

You did good

[gregbradley]

I'm with Peter on this. Its a spectacular image, easily one of the best around. One small area of improvement though would be the dynamic range as he points out. The look is a bit too transparent (or at least to what I am used to seeing in galaxy images). The dust areas etc are a bit too light. Perhaps toying with levels and curves or some previous processing step where stretching changed the dynamic range may get a gain here.

Greg.

[RickS (Rick)]

Thanks for the feedback Peter & Greg. I've been mulling it over and have a couple of ideas to try. Will see what I can do...

[aljo2345]

Very cool!

[Ross G]

A beautiful galaxy photo Rick.

I love the colour and detail!

Ross.

[RickS (Rick)]

Thanks, guys!

[E_ri_k (Erik)]

Beautiful Rick, awesomely done

[RickS (Rick)]

Thanks, Erik!

[David Fitz-Henr]

Superb detail Rick, well done

[Bassnut (Fred)]

Excellent Rick. The Ha was a good move, sharpened it up and bought out nebula in the galaxy.

[RickS (Rick)]

Thanks David & Fred!
