Description

Well here's my contribution to the Helix pics! Imaged over quite a few nights (thank goodness for automation) and after some frame culling (bad seeing, wind, etc) was left with about 31 hours of good Ha and [OIII] data from which I pulled together a bicolor image. Gratifyingly, the faint outer nebulosity revealed itself after a stack and stretch but I decided to leave it a bit subdued so as not to distract too much from the main feature. I did take an [SII] frame just to check, but decided it was far to faint to be bothered with.
