Description

A combination of widefield and close-up, this composite image of Orion is my first attempt at widefield astrophotography.

Taken on a IR-cut Canon EOS 800D with a Sigma 50-100mm F1.8 Art.
250x60s lights at ~60mm, F2.4, ISO 800
45 darks
29 flats
20 dark flats
63 bias

Stacked in AstroPixelProcessor, plus light pollution removal.  Quick stretch in Photoshop before using Starnet++ to create a starless image plus a star mask.

Leveled, stretched, and a light high pass filter to bring out the nebulosity.  Then added the stars back in.  Unfortunately, stretching blew out the Great Orion Nebula, so I had the idea of using my HaRGB+SHO image to bring back the detail.  I overlaid it and adjusted the opacity, gently brushing away the borders to blend it smoothly.  I think it added good detail without drawing too much attention.
