NGC 253 Reprocess

[E_ri_k (Erik)]

So with a lot of help I have managed to learn a bit of PixInsight, and reprocessed my old data of NGC 253. I recon its a huge difference from my original attempt.

What do you guys think?

A big improvement, Erik!

Well i think the first shot titled processed looks better, and they seem to be reversed to each other.
Anyways good effort.

Hi Erik I'm going out on a limb here but personally and IMHO I preferred your first effort all along, even above the tweeks by others.

I think your original image just needs some blue regions "star growth activity".

As a yard stick here are two images of NGC 253 one from APOD and the other from WIKI.

Thanks Rick. I'm not sure what happened, but yes, it's been mirrored somehow, I didn't even notice! I might have a play with my original in PI as well and see what I can do. I prefer the second, I think it's got more detail and better colour.

Thanks for looking.

Personally I love the colour of the reprocessed one, but the tone of the original. So much detail in the dust lane seems in my opinion to have killed that soft centre glow from the middle of the galaxy.

That is just a personal preference though. The second one really does look sharper and more detailed.

Hi Erik,
I hope you don't mind.
I combined both your images 50/50 opacity & played with the curves
to reveal the barred spiral.
What do you think?
(I had to flip one image & play with transform & warp which left slight star misalignment.)

[E_ri_k (Erik)]

Not at all. I like it. I know what you mean, Is has lost that central glow. It looked really good at the time, but now I'm not too sure now. Your version is a good compromise between the both.

Thanks Erik,
I think your data is good enough to re-process a little.
Blending an older version with a later is often a good method.

cheers

Two very good photos Erik, but I prefer the less colourful original.

I like the reprocessed one better, but the combined one by Allan is great, too.
