M39 - Open Star Cluster in Cygnus

M39 is an open cluster made up of around 30-50 stars in the summer constellation of Cygnus the swan. It is located around 800 light years away (1 light year = 6 trillion miles) and is estimated to be around 300 million years old. These stars are very young and hot which is shown by their blue colour, compare these to our star which is 4.5 billion years old.

With the constellation Cygnus lying on the galactic plane, the cluster sits in front of millions of other solar masses that make up our Milky Way galaxy, and this is only a tiny portion of our night sky.

The aim here was to use longer exposures to try and bring out some of the dust globules in the area which you dont see captured too often. I did pick up a little but sacrificed star size. Other than star reduction in Photoshop this was my first image processed entirely with the trial version of Pixinsight, a piece of dedicated astronomical image processing software.

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.
