Messier 39 before the invasion of the streetlights

I love the background star field in this image. Pixel peeping will show a few camera anomalies that I had to work around. There are several dark clumps for fewer stars visible.

One of the first times that I was able to use Photographic Color Calibration and get a result that did what I wanted it to do; bring out the individuality of the backdrop to the cluster. Several red giant stars are visible, brought out with a touch of saturation.

This image was taken about a month before the city installed all new streetlights that took the house from Bortle 4 to Bortle 6(!) (corrected in comments). Before the streetlights I was measuring an MPAS of 21.10-21.20 on clear nights. Now I barely hit 20.00 with the same meter. Not nearly as bad as some of the people out there, but a bad trend.

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.
