Messier 37 is a striking open cluster in Auriga with a mix of red giants, white dwarfs (not visible here) and mostly bluish medium aged stars.

The brightest red giant, HD 39183, is the magnitude 9.2 star near the center of the cluster. The white dwarf stars are around magnitude 23 and are too dim to show in this image taken with an 8" reflector.

Esitmated to be around 5000 light years distant and 40 light years across, M37 is well-worth a visit when visually observing in the northern latitude winter skies.

I captured data for this image over 26 sessions between Sept 2020 and November 2021.

Calibrated with SiriL and gess, registered, stacked and post-processed in PixInsight.

Thanks for stoppng by!

Title: M 37 Core at 1:1 Zoom Level

Description: A 1:1 zoom level look at the core gives a better sense of the many stars in the cluster. Some of the stars are field stars not associated with the cluster, but nevertheless, a very rich and colorful region.

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.
