This has been an interesting one to get in a place where I really enjoy the image. I have gone through this data a number of times, and this time I tried using the GHS tool for the stretching process and that was the magic bullet to help get everything in the image finally where I wanted it. For the HA, I used the continuum subtraction method (https://www.nightphotons.com/guides/advanced-narrowband-combination) which significantly improved the details obtained from the HA details in this galaxy. I will be using this for other projects in progress that also will be galaxy images with HA captured for them.

Overall, a much needed improvement. I will likely go back to this over time, but for now I am pleased.

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.
