Beschreibung:

Update 2014 Mar 23: Replaced it with better noise reduction. Probably not noticeable unless you look at it zoomed. It does have slightly better fidelity even at gallery size, though.

Messing around with the cone nebula and seeing what had already been done with these data I discovered there are some interesting structures which become hidden if you try to cram the near-infrared and H-alpha both into the red channel where they technically belong. I am probably committing some form of processing heresy by representing H-alpha with blue-green but to hell with convention. Please compare it with this image, at HubbleSite.

Reddish orange colors are representing near-infrared data. Greenish blue colors are H-alpha. Blue is a wideband blue filter.
