Revision title: Final

It is nearly a year since I last imaged the double cluster with my mono CCD camera and filters. Imaged this year with my CMOS OSC camera and inbuilt UV/IR filter, this comprises just 20 minutes integration using 60s exposures, to fill in time before Andromeda reached sufficient altitude to clear the light done of Aberdeen. Nothing else really needs to be said, except that it is one I always turn to when observing visually - a treasure trove of older red stars and younger bluer stars.

[Postscript - some nasty gradients, I expect caused by dew collecting on the objective, and unsteady seeing at the start of the night].

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.
