I think I've missed the best time to be shooting this - although it depends when the next clear sky comes round! With a very big moon and a small window I decided to to go for it. I'd been looking for some interesting star clusters that had galaxies in view and found this - so framed things up and got started. Trying to get galaxies was a mistake with the moon less than 90degrees away - I knew this but had some optimism I'd get something. When the cloud parted I got just under 2 hours before it set behind my roof.

Collinder 21 (Cr21) is the "D" shaped asterism in the bottom left. As well as the NGC and IC galaxies, there's the usual peppering of PGC entries. Getting any colour in the galaxies felt like a no-go - it was all too washed out.

I'm posting this anyway as I don't want to lose these frames in the archive and forget to go back to it this year or another.

Thanks for looking.

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.
