NGC2168 + NGC2158 (Open star clusters in constellation Gemini)

A very rewarding object in binoculars, NGC2168 was discovered in 1745 by Philippe Loys de Chéseaux and Charles Messier added the object in his famous catalog with the entry number 35 in 1764. This small patch of stars can easily be found in the constellation Gemini (the Twins) near the feet of Castor, between stars Eta and 1 Geminorum (visible in this photo). At a distance of 2,700 light years, M35 is visible as a mottled, misty patch to the naked eye under the relatively dark skies where I live. The open cluster also contains several yellow and orange giant stars of late G and early K type that shine with a total magnitude of 5.1. This image was taken during a full moon.

NGC 2158, a more compact open star cluster, is visible immediately below M35.

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.
