M7 - Ptolemy's Cluster

Ptolemy's Cluster (Messier 7) is one of the most beautiful clusters, to my eye anyway, because of its location in the heart of the galaxy. So the cluster has the backdrop of the multitude of stars, gas, and dust that constitute the morphology of this part of the sky.

According to Messier-objects.com, this cluster is about 220mm years old lying approximately 980lys from our solar system. There are about 80 stars in the cluster, many of which are very massive young blue stars.

From my location, this object is very low on the Southern horizon. But I think I had pretty good seeing last night an came out with a passable image. There s just so many interesting things in Scorpius and Sagittarius that I am trying to image them even though they are not well placed for me at my latitude.

Anyway, any comments/criticism always welcome!

CS to all!!

Description: this one represents a little different approach to the stretch. Perhaps the bright stars look a little better? I backed off a little on the lightness which I believe results in a more realistic depiction of the cluster as well.

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.
