I know you like this nebula pics Tane so here is one i thought you might found neat.

Origins: This is a real photograph of the Helix Nebula, although it's technically not a single photograph but rather a composite image formed from several photographs taken by NASA's orbiting Hubble Space Telescope and a land-based telescope at the Kitt Peak National Observatory near Tucson, Arizona.
This image was NASA's "Astronomy Picture of the Day" for 10 May 2003. The picture's "Eye of God" appellation appears to have been a title coined by an admirer of the photo due to the nebula's resemblance to a human eye, not something designated by NASA.

maybe tane can answer this one: the color of the image is not actually from the photograph, but is added in by artists? or is it a composite image from the different filters used by the cameras?

What they do is take several long (and I mean LONG :)) exposures of the nebulae or galaxy or whatever with different filters then use RGB filters to add colour (sometime color is naturally there, but never alot and almost always very faint, most the time they look greyish and dim). It's a very long process but comes out looking most the time like that. This picture took 9 orbits for Hubble to take then was blended with a views from the Mosiac Camera at Kitt Peak in Arizona to make it so detailed.
Some pictures you see of planets or nebulae are only taken in segments and need to be digitally enhanced and corrected and blended to make them look perfect. As I said, it's a very long and time consuming process but the end result is always WELL worth the effort !!
