Many people tell me that my photos have not colors. Well, I hope have not done too much :question:

Same way. Did I boosted too much ? :question:

M8 looks good. M20 might be a bit too much saturation?

Thank you, Kevin. I must agree with you. I feel the same.
A bit less than UUSS Trifide Nebula :rolleyes:
Nice job Jorge. i really like the reprocesses

Thank you, very much, Rex, Laurie, Ross G and Steve . Mainly to Ross by observing my evolution.
To Work with colors in astrophotography is a source of discussion.
Today we can manipulate with colors having previous images from objects. Example: Trifide has blue and red as main colors.
But if you are in previous age, when nobody had imaged this object, yet. You are the first. With no sophisticated equipment to analyse the spectrum of the photo. How to decide about what boost ?
You can not see the actual color of Trifide with your naked eyes. Nor can go there to see it.
Red passes through our atmosphere more easily than others colors. Blue, our atmosphere has this color by chemical composition.
But as the first shooting Trifide, you have no reference to deal with its colors. Why not green, pink or yellow ?
If you decide to boost the green and red or green and yellow... It is done. Became a reference, up to a photo with help of spectrometry recover a better reality of the possibles colors.
NGC 5128 is a good example. Some photos the clouds are fully yellowish. Others, they are black with some details yellowish. How colorize this DSO ?
I reckon the better work is when the details takes more importance than the appearence. I am not sure, yet, but I reckon it will be my goal

How about using a standard unmodified DSLR as
a reference for the correct colours?

i really like the originals........ much more subtle and it draws my eyes to the core

I have watching your images for months now, you are certainly persistent, and the results are showing great improvement. These last images are very well captured and processed. I like the first ones in your initial post. I like "over cooking" my images, I'm trying to stop that, but a little more colour in these first images would be okay, but just a little more.
Keep up your good work,

A fine set of images!believe of not, I really don't like getting into discussions on color because there is no guarantee that we all see colors the same way.
Personally,I feel that contrast is the way to a great image.

Thanks, all you, for looking and commentaries.
Sorry, but I did not understand very well your suggestion. I use an unmodified Canon Rebel XT DSLR, and it seems there is some lack of blue, and excessive yellow-pink in my original photos. To show a better colorized image, I must work them in Photoshop. As I do not know about all DSOs, some times I have some doubt of which color to boost. Normally I work with them before to search in internet.
Pat, I agree with you
Steve M, thank you for looking my improvement.
atalas, as a I said, I reckon I'll prefer to prioritize the details
