M33 Triangulum Galaxy (Wide)

Partly taken while on vacation in Colorado (120s subs, no filter), and partly at home (240s subs, ZWO Duo filter) in my backyard.

I spent quite a lot of time trying to get more of the red Ha regions to show up in this image. After processing the image, I went back and integrated just the images that I took at home with my ZWO DUO filter, and then I extracted the red channel, which is a 12nm bandwidth filter, to give me Ha data. The part I could use help on is how to combine that red channel with the rest of the image. As a temporary method, I created a mask from the red channel and used that with Curves Transformation to enhance the red parts of the image.

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.
