SH2-73 - molecular clouds in Hercules

As Barry Wilson mentionned recently is not a sharpless nebula .

From Sky and telescope : "Sh2-73 is located in the constellation Hercules and was mistakenly included in the Sharpless catalog as an emission nebula. We now know that the nebula is simply a molecular cloud. With its relatively high galactic latitude, about 45°, the integrated light of the galaxy illuminates the nebula. Therefore, we can refer to Sh2-73 as an integrated flux nebula, as defined by Steve Mandel."

If you look attentively , you will detect some very nice small galaxies all around the field

Just added an annotated version :-)

75 Light subs @180s gain zero and -15°C and

17 Blue subs @180s gain zero and -20°C

20 Green subs @180s gain zero and -20°C

19 Red subs @180s gain zero and -20°C

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.
