NGC 6823 HaRGB

Wasn't sure how to best identify this one. I used the Ha integration as the luminance (both stars and nebulae), but I didn’t add Ha to the color data. Though it killed me to toss the Lum data I collected, no matter how super (duper) I tried to make the luminance by combining it with the Ha in a variety of ways, even tossing in an R,G,B integration luminance, in the end the Ha integration alone carried, by far, the most detail, so I came to terms with the Lum data as sunk cost and went with the Ha. On the other hand, adding the Ha to the mostly red RGB just made it, well……redder. Not really adding any information about the target, nor, even, providing any aesthetic benefit, so I only used the Ha integration to replace the luminance.There were a couple other processing idiosyncrasies. For one, DBE and Graxpert produced very different results, though probably not surprising since my DBE grid only consisted of 6 points total because of the lack of background sky, where GX’s default grid pretty much covered the whole image with just a couple gaps. Not sure which, or if either, is valid, so I ended up blending stretched versions of all three; DBE, GX, and no background removal. Also, when stretching with GHS, RGB mode was much more saturated than the Colour mode, so I would start with Colour and increase saturation by moving the slider towards RGB, instead of the other way round.

This target is also the first time I've used an Ha integration as a luminance layer for the stars. Recently I've been using just RGB stars (not LRGB) but thought I'd try HaRGB, and in this instance at least, I'm happy with the results.

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.
