Gum 15 (RCW32) in HaRGB

Gum 15, also known as RCW32, represented in HaRGB. Another one of my "milestone targets" as I imaged this target about two years ago when I was using a DSLR. The comparison now with the QHY268M is stark to say the least. Spent the better part of two afternoons processing all that data and fine tuning the final result. I noticed the RGB image had some faint reflection nebulosity so decided to incorporate some of the RGB luminosity into the Ha for better representation. From a test exposure, I saw this nebula has a little [SII] but [OIII] was absent altogether so no SHO Hubble palette unfortunately.

Title: Gum 15 (RCW32) in HaRGB - Revised

Description: Decided to revise my HaRGB on Gum 15 to give a look that I feel better represents the various aspects of the object. The original image is heavily weighted towards H-alpha but after further hybridizing the HaRGB data, I could make out a lot more of the dark and faint reflection nebulosity that the Ha doesn't pick up nearly as well but is strongly represents in RGB.

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.
