Howdy.

I like this a lot, it is a great image, nice and smooth, nice star colour and galaxy structure although I think it could look a bit better.

I would colour calibrate the image to reduce the purple in the galaxy, get rid of some of the green in the image, add some light saturation to bring out the blues and whites in the whole galaxy structure and darken the background by a tiny fraction.

Anyway, it is great as it is so tell me to go suck lemons if you want!!

Thanks for the full res.
I think it needs a few very fine adjustments to be perfect but you're 99% there.
A bit of HLVG in Photoshop would take the slight green out of it.

cheers

That's very fine, Diego. Nice work.

Good to see you posting full size images too.

[Ryderscope (Rodney)]

A nice M83 Diego. I'm glad to see that you found M83 in your new piece of sky. Am looking forward to more images from the new place.

[Atmos (Colin)]

It is a detailed and smooth image Diego

[Octane (Humayun)]

Well done, mate. That looks fantastic!

That looks fantastic. Those exposure times seem just rediculous to be able to pull that much detail. Very nice.
