Description

The Orion Nebula is often the first object we shoot when starting deep sky astrophotography. I think I've shot this with every set of equipment I've owned! I had some data from two years ago that wasn't sufficient so I added more this year with the goal of going deep. I wound up with 35.8 hours of usable primary data plus 3.25 hours on the core.

The core is comprised of 120 second subs, all RGB as there was no need to shoot luminance when the object is too bright to start with. I pulled two separate stretches from the core data to try and resolve the Triangulum as best as I could. A round of shorter exposures is probably needed.

The background is 17-18 hours per side and I pulled two separate stretches from each master. One for the dimmer bits and one for the brighter parts.

LRGB masters were assembled in CCDStack. The different stretches and the core were assembled using layers in Photoshop. After joining the Mosaic in Photoshop, I took a 16bit master back to CCDStack for deconvolution and sharpening. Then back to Photoshop for final processing.
