During the last full moon phase I decided to shoot the Iris in the brief time before the moon rose each night, then once the moon was up I switched to a different target with narrowband filters. It was fun shooting two targets per night, but with the short amount of time with no moon meant the Iris took many days, and after throwing out some frames I wasn't left with a whole lot of time. But I am eager to move on, so processed what i had. I may come back to this one and add more data later but happy how I was able to get some of the dark dust clouds even with fairly short time.
This is subs from 6 different days, I didn't bother to break out each day in the info, from Sept-24 through Oct-5. With so many different days and different temperatures it was going to be quite a hassle applying calibration and I didn't shoot flats most of those days nor did my darks match for each. Siril is great but processing different days data is quite a manual process. I did try using some calibration but the results weren't better. For the final edition I hoped that dithering was good enough for noise and to be honest the software took care of vignetting pretty well, I did better without any calibration.
The biggest thing I'm not as happy about is using Starnet++ to remove the stars so I could stretch the background more to pull out those dust clouds. I never can add the stars back in without some dark halos. Still practicing with different editing methods there...

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.
