I've been trying to image this nebula since late summer. Its not a lot of light to work with (for me anyway), but the combination of a narrowband filter (DGM Optics NPB), integration and the realization I could manually rotate the camera between image sets (3 second exposures, with live stacks of 167, 178 and 167 frames). I am reasonably happy with the result, although the NPB filter caused a large circular reflection artifact around bright stars. I ordered a newer generation narrowband filter Optolong L-eNhance so hopefully I will be able to reduce in the not so distant future. I used Pixinsight to register the 3 images from live stacking (StarAlignment) and to integrate (Image Integration). Color was calibrated with Background Neutralization and Color Calibration. No background noise reduction in original integrated image. I just went with Pixinsights stress and some minor adjustments with Curves.

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.
