Description

Astrobin processing challenge of the Pencil Nebula, from data acquired by Greg Turgeon with a CDK17 in Chile. A dramatic nebula with a ton of Oiii signal!

This is approximately 30 hrs of data in Ha / Oiii / LRGB.

I processed using a tone mapping approach with synthetic luminance constructed from Ha augmented with starless Oiii and L.

Most of processing done in PixInsight, final color tweaking in Photoshop.

Thanks for looking!
