M7 RGB (OSC) - Ptolemy Cluster

The Ptolemy Cluster (named after the greek polymath) is one of the few easy naked-eye clusters (although easy is a subjective measure). Viewing from the shore of Sardinia it was easy enough if you know where to look as the MW isn't as thick there as further north (or south, as I may speculated based on pictures). Nice problems to have...

Anyways, the issue is still present when we turn to wide field pictures taken with fast lenses. My instinct would be to use curves to push the mid-tones up but that renders the contrast between cluster and surrounding star field less pronounced. So, against my instincts, I decide not to push it and leave the whole tonality a notch below what would be otherwise (e.g. the Pipe Nebula picture).

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.
