#Could someone try editing this and explain how you did it (Orion Nebula)

Here is my process:

First I remove the background gradient with GraXpert. The program creates a grid of points, calculates the background and then subtracts it. The preview does usually not look to great, but as long as the brightness is even that's ok. 😉

#

Then I do a basic stretch on the data (levels and curve adjustments) in Affinity Photo. The stretched image should not be too dark:

#

After that I crop the image to final dimensions, denoise it and run StarNet to separate the stars.

#

Now that the stars are gone I bump up the contrast and color (also Affinity Photo):

#

Finally I add the stars back.

#

It's not my best edit, I had limited time, but I hope the information is helpful. 😄

What????? That looks so good

#

How is it so clear?

#

Is that from my stacking?

How did you get so much color?

#

the processes I did in order (in pixinsight):
Crop
DBE
Colour calibration
Blurx
EzSoftStretch
Noisex
Curves
Local histogram equalisation
Curves

Aside from a few tools only in pixinsight, a lot of this can be achieved with similar things in other software (e.g. blurx is just a deconvolution algorithm, noisex is denoise, ezsoftstretch is just a fancy histogram stretch)

Do you need a license to use PixInsight? @shrewd jetty
