M33 - LRGBHa

I have been going back to my NAS and started processing data that I didnt do a good job first time around.

This is an interesting target to process. The data is easy to collect with this being well positioned and bright. The Ha is abundant.. with lots of structure. However,
processing it throws rather interesting challenges. The star clusters in the galaxy itself gives it a crunchy look and star reduction tools completely destroy it. Adding Ha overwhelms the image with red knots all over. Every attempt I did with star removal resulted in weird star artifacts and I finally stuck the "traditional" processing of L and RGB. Ha was added to both RGB and L and then was processed as regular LRGB image in Pixinsight .

The Ha is added as mouse hover image to show its abundance on this target.

L - 64x5 mins
R/G/B - 15x5 mins per channel
Ha - 40x10 mins

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.
