Messier 35 and NGC 2158 Open Clusters in Gemini

From Wikipedia:

Messier 35 or M35, also known as NGC 2168, is a relatively close open cluster of stars in the west of Gemini, at about the declination of the sun when the latter is at June solstice. It was discovered by Philippe Loys de Chéseaux around 1745 and independently discovered by John Bevis before 1750. It is scattered over part of the sky almost the size of the full moon and is 2,970 light-years (912 parsecs) away. The compact open cluster NGC 2158 lies directly northeast of it.
NGC 2158 is an open cluster in the constellation of Gemini. It is, in angle, immediately southwest of open cluster Messier 35, and is believed to be about 2 billion years old. The two clusters are unrelated, as the subject is around 9,000 light years further away.

Two very pretty open clusters in a fine star field. Distinct difference in appearance, where M35 is mainly comprised of young hot blue stars and NGC 2158 is primarily older yellow stars.

To me, NGC 2158 steals the show. It is about 3 times further away than M35 and is almost 20 times older (110 MY to 2BY).

The data was drizzled 2x and many tiny binary star systems can be seen when diving in!

Thanks for looking and comments welcome!

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.
