M72 represents the 39th Messier object I imaged over the past 6 months. It is located approximately 58,000 light-years away in the constellation of Aquarius, contains over 160,000 stars, and 9.5 billion years old. Although it is considered large at 100 light-years across it appears faint do to its great distance. I managed to get 18 - 90 second sub-photos out of 32. Unfortunately wispy clouds moved in. Although weather was not cooperating I did get a chance to use my new Agena StarGuider II 50mm Mini Guide Scope with Helical Focuser. It worked perfectly with the autoguider. The Orion ST80 worked well but I wanted to lighten the load on the mount. Also, I should be able to use this with my 8-reflector on the mount.

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.
