There are unlimited ways to process an astronomical image. Every imager has his/her own taste for the 'pretty picture'.
Some halpha imagers process by inverting the B/W image.. and then add colors to the image. It makes the filaments on the surface look like 3 dimensional.
I did just that with the following image and to me, it seems the 3D effect does appear with this processing technique.. what do you all think about it?
