M36 and M37 - open clusters in Auriga

The first clear sky in a while. I had planned a wider field image of the emission nebulae in Auriga, but for some reason my little RPi4 Stellarmate would not plate solve with my camera lens setup.

A bright moon was so interfering, and with the temperature dropping, I left it to it, taking 3m exposures of the glorious starfield and open clusters in this constellation.

I kept 43/59 frames calibrated and stacked in ASTAP, and processed in Siril. As ever two (or more) versions, as I experiment with different approaches and processes. The background is definitely better in 2x2 binned, and the faint nebulosity shows up.

I will need to use NB when I home in on the flaming star and wonderful emissions that make this such an exciting area to image. Hopefully another opportunity when the moon is on the wane.

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.
