Asterisms (Gary Imm)

Asterisms

So here we are now, scraping the bottom of the proverbial DSO compilation poster barrel.

An asterism is simply a pattern of stars in the sky. The human mind loves to create patterns in order to find order in our chaotic world. Some asterisms are simple geometric shapes comprised of just a few stars in a small area, while others consist of many stars in a large region which are supposed to represent a complex shape. I find amusing the many different complex asterism shapes that I have encountered over the years, most of which I have a hard time seeing or even imagining.

Typically, stars in an asterism are not related and are only lined up at this point in time to our apparent view by superposition.

The poster contains 20 asterisms which I have enjoyed imaging. The technical data for these objects is shown in Revision B.

Each of the objects of the poster has previously been uploaded and described individually on Astrobin. They all reside in my Astrobin Asterism Collection.

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.
