After the quick and dirty first attempt at stacking and processing, I wanted to redo the process to get rid of the green colour cast and uneven brightness and see if I could pull some more detail out of the data.

It’s the same 22 1 minute exposures at 1600 ISO using the FujiFilm X-A3 and Samyang 85mm F1.8 shot wide open. The camera and lens have impressed me even more at how much they were able to capture in such a short time and the overall sharpness of the image. Barnard’s Loop now looks the way it should, and the nebulously linking the main nebulae in Orion is a lot clearer.

Processing in APP was the same apart from using the non-adaptive setting for star colour calibration. The biggest difference came from being more subtle in StarTools to output an image for final adjustments in PhotoShop that had much less contrast than last time. There are still some aspects that could be better such as uneven colour casts, but I suspect that's hard to avoid when enhancing an image so much to pull out very faint detail; especially since I don't really know what I'm doing!

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.
