M17 Omega Nebula in SHO, with the HA From a different camera/filter

July and August have been terrible months for Astrophotography from my location with cloudy nights and rain. I have only been able to image 2 nights so far in August on an M17 project in SHO. M17 is low on my horizon, limiting the time I am able to image it. I have been able to collect SII and OIII data using the ASI294mm and NB filters during the two nights in August, so far. But, the prospects for further imaging this month do not look promising and the window to obtain further data on M17 is closing. I found I had previously imaged M17 back in 2019 with the same telescope, but with an ASI183MC and Optolong LeNhance filter. So, I processed that data as my HA data, converting to monochrome and creating an SHO image with the ASI294mm NB data and the ASI183MC RGB LeNhance data. Some day, hopefully, I can get some proper HA data and reprocess.

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.
