"Pencil nebula" (NGC 2736) - DSW processing contest

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 !

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
