I have been experimenting with the method of adding Ha data to RGB for galaxies shared by Charles Hagen. I found it to be an excellent way to clean up the narrowband data and offer much better control over the NB signal. Many thanks, Charles, for sharing the expertise with the community. For those who are interested, here is the link: https://www.nightphotons.com/guides/advanced-narrowband-combination

I used William Optics Pleiades FLT111 for the image. The scope is very sharp and the image would be undersampled if processed normally. I drizzled X2 and then cropped the image, which is still in a higher resolution than the normal ASI2600MM sensor output. I quite like the final result. Perhaps I will drizzle all my images taken by this scope in the future.

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.
