The Double Cluster, in unfiltered glory

A few nights ago I was shooting Andromeda until the rising moon started spoiling the sky for dim targets, and as an afterthought decided to shoot the Double Cluster after moonrise. Open clusters are often passed over by astrophotographers, lacking the detail of a nebula or the distance of a galaxy. However, I spent hours enjoying the color contrasts, the star pairings, the strings of stars and the pure brilliance of the Double Cluster through my camera's eye. This afterthought photo whets my appetite for doing some visual observing this weekend in Bortle 1/2 skies, where I can collect raw photons into my own retinas.

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.
