Here's one you don't very often - the reflection nebula IC2087, which is embedded in the dark nebula Barnard 22. Since reflection nebula's are normally blue, I'm not too sure why this one is orange(ish)....I guess it must be the combination of the light from the bright blue star (out of frame), which is makes the background blue/purple, interacting with the dark brown/red of the dark nebula.
IC2087 is also known as the little flame which seems appropriate since the stars above it appear like sparks from a small fire. For those with keen eyes, you'll also see a small red blotch above the fire, this isn't a processing artifact but a Herbig-Haro object which is a patch of nebulosity associated with newly born stars.
So, you get quite a few interesting features in this image which was taken with my Esprit 150 and represents just under 10hours integration time.
