For my clydesdale project I made an excursion to modelling space scenery.
I missed good examples in the forum and so I tried to create the nebula with the particel system, with unfruitful results.
Thanks to this tutorial i got new perspectives.
Hope you like it, hints are welcome 
!
The first two pictures are examples from NASA. The third is my blender render.
i think the extra brightness of the yellow/white color in the bottom right must most hide the little white points. It’s an excellent composition
Thanks, yes right.
And I think, it doesn’t look 3D…hm.
Gorgeous my friend, gorgeous.
It looks very well done. I like it. Perhaps a few composite nodes to help enhance the image?
Thanks you all.
Compisite, why not 
!? But what?
Looks good. Your getting closer then most that I have seen.
The stars seem a bit too uniform in size and color. It looks like there are only three sizes.
The nebula could use some more contrast and detail. It’s basically a huge fluid sim to take a look at smoke textures to help you out.
I would also change the colors. Yellow is cool but very bright not typical, if your going for realism I’d do more of a red, blue, purple, orange kinda colors.
As thumbnails I thought they were all Nasa images, then the color gave it away.
Good work! It’s definitely getting there

Yes, there are only three sizes and four colors. I’ll set different distances, this should solve the problem.
This nebula only contains 5 big halos with a procedural textures (each about 5-10 color ramp marks).
You’re damn right! I need more detail, but I don’t know how…hm…trial and error.
Realism means, there are no colors 
- the colors of both NASA images are mapped radation wave length to a defined color. So, the red and orange isn’t real, too. Maybe I’ll try to make a red or blue nebula.
