Description

The famous Horsehead Nebula (B33), discovered by Williamina Fleming in 1888, and Flame Nebula (NGC 2024), illuminated by the star Alnitak (zeta Orionis). HaRGB, with Halpha and R combined using Lighten in Photoshop, and then 20% Halpha luminance added (so Ha(HaR)GB). Would like to reduce the violet halo on Alnitak -- not sure what the issue is there. Still a little time left to get more exposure before Orion sets for the summer, if we can get some more clear nights.
