Description

For this Crescent nebula image I shot 11.33 hours of narrowband SHO data from my yard in Wake Forest, NC using ACP Scheduler over multiple nights starting September 5 and ending October 1. I'd like to go deeper next season and aim for 20+ hours, but this had enough data for some interesting details and a modest amount of noise.

I used Astro Pixel Processor for pre-processing and PixInsight for the rest, starting with integrated S, H and O frames generated by APP.

I created two different narrowband blends, resulting in the two revisions here. One was R=0.5HA+0.5SII, G=0.25Ha+0.75OIII, B=OIII; the other is straight Hubble - R=S, G=H, B=O.
