I added Ha (Hydrogen alpha) to last year's LRGB Horsehead and Flame Nebulas, B33 and NGC 2024.  This was shot from my suburban Louisville, KY backyard.  This target is around the Alnitak, the left-most star in Orion's Belt, and the bright monster star above the Flame. 

It was shot with my ASI183mm-Pro and ZWO 36mm Premium RGB filters, using my Esprit 100 with the TSAPORED075 FF/FR at 413mm, f/4.13.   Processed with PixInsight.  I added Ha to Red &  Luminance, and I did a several extra PI processing steps.

Lum           30sec x   226
Ha            120sec x  140
R               60sec x    95
G               60sec x    95
B               60sec x    96
