M67 : Amas du Cobra Royal / King Cobra Cluster

The King Cobra cluster in an 4 billions years old open cluster at 2600 light-year distance. It is quite old for an open cluster, most of them are dispersed for long ! But M67 remains quite compact, with around 500 stars concentrated in a 20 ly area .

M67 is quite old, so there s no blue giant left. Most of stars are simular to the sun, some are F type. In the image, theses stars are probably faint white stars in the cluster. Sun would have a very faint 14 mag but should be detectable. Some are now old enough to be red giant stars. The contrast of colors of these stars make this stars quite beautiful in a small telescope view.

In this cluster, there are "blue stragglers". These stars should be red giant for long, but may be they were made of a collapse of two stars.

For astronomers, this cluster is quite interesting because of this age close to the sun one and 100 stars similar to it. Thus, it should be interesting to look for exo-earth.

It is hard to understand why this cluster is named "King Cobra". It seems that it looks like a head of Cobra. May a faint drag toward the right corner acts as the body of the Cobra.

This image is shooted with a 80 mm refractor and a ST8-XME with only 17 min of luminance and 20 min for the color . So constrast is not fantastic caused to a lack of exposure and light pollution in small village 35 km far from Paris. Faintest stars are about 17 Mag.

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.
