yet another helix nebula
Hi All, here's my rendition of the helix nebula. It definitely goes into the "purty pitchers" category, certainly not an unadulterated pure science image, but I wanted something that looked nice because I'm pretty new to pure narrowband imaging.
I went pretty deep with around 50 x 20 minute exposures in order to get the outer wisps in Ha. I used Ha luminance layer and red channel, oxygen for blue and green, and sulphur for green too (not many sulphur photons).

the rest done with layers in PS and LR
