Description

Many friends at FWAS have been publishing Ha images and I didn't want to be left out, so here is my first

I have SII and OII data, plus RGB for the stars, just haven't had enough time to learn how to process the whole image. Meanwhile though here is just the Ha integration.

I'll update this once I figure out how to use PI's HDRMT process to calm down the brightness of the Orion Nebula

Played with PI's HDRMT process today - what a brilliant tool! I successfully managed to compress the dynamic range of the Orion Nebula and extract detail that was completely obliterated by the almost-saturated center. After that I really struggled with how bright the Orion nebula should really be versus the much dimmer Horsehead and Flame Nebulae. Please let me know what you think.

Description: Really trying hard to get the right balance between color and contrast in this image. The biggest difference is how I stretched it using GHS, and then how I created a luminance image for HDRMT. I also tried to blend in the blue channel from my RGB frames, but that didn't give me the impact I wanted on the color of the running man nebula and the flame nebula.
