'Cosmic Kite' - HSO - Pickering's Triangle - NGC6979

Notes: I really had difficulty deciding on how to process this data. My overwhelming instinct was to disregard the Sii data and produce an HOO image. In many ways the HOO image rendered better details through greater contrast, but I couldn’t shake the feeling that a narrowband image which includes the Sii would better showcase the true nature of a Supernova Remnant, as an incredibly violent if beautiful mixing pot. So, long story short, here is my HSO Cosmic Kite.
When combining the channels, I experimented with Pixel Math, making various channel combinations until I settled on adding a small percentage of the Oiii to the Sii to create the Green channel. I then used a standard Pixinsight workflow on both HSO and RGB stars before combining in Photoshop.

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.
