Nice separation of bright stars from the star cloud behind.

Great data but your processing is a little off. Check your histogram for color balance. The reds need to be toned right down and the data is a little clipped as well in the greens and blues. Worth a repro because the field is very well captured.

What Marc said

Its a fantastic field of view. With some minor tweaks I'm sure you can make this image really shine. Looking forward to more.

Hi Luiz,
I agree with Marc.
The data is great - just needs better stretching & color balance.
Well done.

cheers

I think it looks good a bit red Luiz

but I guess you could have a play and see if you can get the star field a tad more golden

.

Lovely field that

Thanks a lot Cam, Marc, Jase, Allan and Mike, for your kind comments and thoughtful suggestions. This is one of my first astro-images in color, and there is a lot of details that I'm trying to grasp. I have assembled an image with hopefully better balanced colors. I hope the stars are golden now!
