Messier 11 - the Wild Duck Cluster
---
The Wild Duck Cluster (also known as M11 and NGC 6705) is an open cluster located in the Scutum constellation. It gets its "popular" name from the way its brightest stars form a triangle resembling a flock of ducks. But, in my eyes, it can also resemble a single duck, if you look at it from a certain angle. 😄

Unlike the more gravitationally bound globular clusters, open clusters are only loosely bound by gravity and comprised of much "younger" stars. Of course, on a cosmic scale, the age of these "young stars" is still measured in 10s to 100s of millions of years. M11 is ~6,200 light years away from Earth, containing over 2,900 stars.

This image was a "collaborative" attempt with a colleague who owns a SkyMax-127 AZ GoTo. While an alt-az mount isn't too suitable for accurate (and long) tracking, the results were still pretty good - also owing to the fact the session took place at a rather dark location (Bortle 3).

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.
