The Helix Nebula

Helix Nebula

NGC 7293 – Helix Nebula

Often depicted in various ways as an “eye” in space, the Helix Nebula (NGC 7293) is definitely one of the more awesome planetary nebulae out there.  It’s a fantastic example of a star that has gone nova after it’s outer shell of gas has been blown apart, leaving a white dwarf at the center.

This was one of a couple images I captured from the SkiesAway Star Party at Joshua Tree last weekend. Conditions were great all three nights so we started collecting as many photons as we could.  At f/6.3, I had to stay with each object a while to get a good amount of exposure.  The Helix is a somewhat low contrast object, but photographically it has amazinly vibrant colors.  I did not ambitiously boost the saturation or embellish the colors in this image – it’s what the camera picked up!  I actually did very little processing “trickery” at all, mainly just PixInsight’s DBE to help even out the background, and basic curves stretching in Photoshop.
