Sh2-261 Lower's Nebula

This is Lower's Nebula photographed from KAUST University campus at the shores of the Red Sea (Bortle 8). Starry skies in Saudi do not necessarily mean that it's good for astrophotography. Dust and aerosol in the atmosphere are a thing here in the region that prohibit good astrophotography sessions, even if no clouds are in the sky. At home in Europe, I check the forecast for clouds; here, I look for dust and aerosol. However, I took the subframes for three nights with increasing dusty conditions in the last few weeks, but I think the outcome is not too bad after some efforts on PixInsight.

Description: I masked and darkened the background to enhance the contrast. I also cropped it for slightly better framing.

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.
