M35, NGC 2158

Two clusters, one relatively close and young, and the other further away and much older. M35 is the widely scattered blue cluster in the center. NGC 2158 is the older yellow / white cluster in the upper right quadrant. M35 contains about 400 stars, and resides about 3800 light-years away. NGC 2158 is around 3 times further away with unknown number of members (likely several times M35?). It is possibly as old as a billion years or more (Wikipedia). NGC 2158 was once thought to be a globular cluster due to it's appearance, but is now easily defined as a tight open cluster. The pairing demonstrates nice contrast and color, sitting in a fairly rich background.

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.
