Red Mars, Blue Stars

Revisiting some old data from my (relatively) early astrophotography days with my improved processing skills, so I feel comfortable sharing here!

On March 3rd 2021 Mars passed close to the Pleiades. Despite less than ideal conditions and a narrow gap between trees I managed to get 40 minutes of noisy data. Happy I got the color contrast, and even picked up some of the reflection nebula around the Pleiades. I revisited this using StarNet V2 to give me more opportunity to stretch the nebula, and also needed to generate a synthetic flat in Photoshop to get rid of a light pollution gradient. As this is from a while back, I didn't have all the calibration frames (including flats) that I would typically use these days. Still glad I managed to salvage something from this!

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.
