This is a single frame of what will hopefully be a 4 frame mosaic of this region. The incredible number of stars in this image obscure the underlying structures, but I find both revisions fascinating for the capacity to display the vastness and complexity of our universe. Any comments/critiques would be well appreciated.

Data were acquired at my parent's cottage in a (grey Bortle 2) in cottage country, Ontario.

The final images are more of an experiment in presenting the low-level dusty parts of the universe. I wrote an algorithm in Python to eliminate the smaller stars, trying to minimize distortion as much as possible. I am still tweaking the algorithm, but may upload it to GitHub once I am happier with it. Any comments on the star reduction would be much appreciated as well.

I hacked the algorithm to protect both the fireworks galaxy and the globular cluster. It was hard to find a satisfactory way to present them without creating funny artifacts.

Description: This image is star eliminated with my own python star elimination algorithm and then the stars are slightly reduced with Pixinsight to reduce how bright they appear with 10min subs. I hacked the algorithm to protect both the fireworks galaxy and the globular cluster. It was hard to find a satisfactory way to present them without creating funny artifacts.

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.
