Based off stuff I've read  on various sites, and especially Monsoon's excellent freebie space scene on 3DCommune :)

Hm, no text have I made you speechless? :>

Just checkin out the tute...I don't get too far as my box is sloooow, but it looks quite good....have you tried clicking on Volumetric material and applying a Volumetric Cloud texture/Mat yet...too much for this old box but would love to see the results. Then you could fly thru Volumetric Nebulae...could be cool

Nice work by the way...

Thaks Bobby :))

nah doesn't work with volumetrics, alas, wlll, only tried it a few times...hm...worth checking later I guess ;)

Thanks!  This looks neat. 

Hey, that's a great tutorial, thanks for sharing... :)

It does work with volumetric materials. That's what my commercial Cosmosphere uses in the Commune store.  The ones in free stuff used a cloud material.....  If you use volumetric materials, then you have to find a good distribution function or image map and set the quality down to medium or it'll take a long time to render.

oh! :)

and thanks Monsoon bows :)

Very nice tutorial. 

I've been doing something similar recently to make mist, clouds and smoke except mapping multiple spheres arranged in front of the camera.  That bit of luminous makes a lot of difference.  I found putting a filter in between the combiner node and the transparancy gives a lot more control over the final outcome too, don't know if it would make a difference to your nebula but might be worth a try.
