The Lagoon Nebula, Messier 8, in Sagittarius

In spite of thin high clouds I challenged this attractive southern gem of a nebula.

For the first time, the software Starnet++ came in and proved invaluable. After processing the DSS stack in Photoshop CS2 so as the stars look good without bloating, I had Starnet++ produce a starless image (it takes a few minutes) and added a layer of it to the project Photoshop. The starless layer can then be processed independent from the base layer hence without affecting star quality and finally "Lighten"-blended with the base image for final touches and tuning. The only drawback I felt was an increase of noise when combining both layers. Perhaps merely a result of inexperience.

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.
