Description

This is the Helix Nebula in narrowband (H-alpha and OIII). I tried to capture a lot of the extended H-alpha halo —the intricate filaments in the bow shock at the left are especially appealing.

I struggled to stretch the object enough to make the extended structure visible without either 1) blowing out the much brighter core, or 2) flattening it so much the eye no longer perceives it as luminous gas in space.

I shot about 40 hours of data, though I ultimately discarded a good fraction of the subs that turned out to be contaminated by light clouds.
