      Description

      The wait is over as color kicked in (Ha and O3 filters) ;)
      The B&W version of this image teased people a few days ago : https://www.astrobin.com/tm37pf/

      O3 data are a mix of Sigma 105 from my friend Victor (https://astrovirusblog.wordpress.com/) that I mixed with O3 data (Canon 200mm) I already had for  the NA / Pelican area and butterfly crescent area.
      O3 data are from three different filters Astrodon 3nm for Victor's data, Chroma 3nm for the NA/Pelican and ZWO 7nm for Sadr (just look at the terrible signature halo on Sadr...)

      Pre-proc in APP
      Proc in Pix as usual.

      The blend is a custom one trying to get closer to what you would get with SHO filters as plain HOO is definitely not my thing.
