Description

By far my most ambitious project yet, a narrowband/RGB combination high-dynamic-range image of the Great Orion Nebula.

Had a slight miscalculation with my blue frames.  On the original night, I lost the majority of my blue frames after the rig scanned over a tree.  The second night, I forgot whether I set the exposure to 10s or 30s, and went for 10 seconds.  However, combining these with the 30s frames turned out fine.

I originally planned on publishing the SHO and HaRGB seperately, but I found a cool plugin on PixInsight (likely from the iDeviceApps plugins) that allowed me to combine my narrowband with my RGB image.  On top of the Ha, Sii, and Oiii each being comprised of a triple-exposure HDR image, this created some incredible depth to the image.
