Description

My version of the "Pencil nebula" (NGC2736).

Acquisitions by Greg Turgeon (@gregturgeon_astro), who has graciously provided it as part of a contest, thanks a lot Greg ! :)

Setup :
Telescope: Planewave 17” CDK - Camera: FLI ML16803 - Filters: Chroma LRGB 8nm - Mount: 10 Micron GM3000 - Location: DSW, Chile

L: 24x600" - R: 24x300" - G: 24x300" - B: 23x300" - Ha: 22x1800" - OIII: 17x1800"
Total : 30h

LRGB-Ha-OIII version - Processed with Pixinsight & Photoshop

Some details about the process : classical processing of the individual images, maskedstretch histogram editing for O and H images, assembly of a luminance mix with L, H and O layers, HDR composition used on the luminance LHO mix in order to gain some details in the filaments of the nebula - assembly in LRGB then addition of H and O layers via PixelMath in starless mode, final color and saturation adjustments on Photoshop. I deliberately chose not to saturate the sky background with the H and O signal in order to preserve a higher contrast for the nebula. I tried to crop as less as possible.

Hope you will like it ! :)
