The Barnard 343 region, next to Gamma Cygni

B 343 is one of the dark nebulae in E. E. Barnard’s catalogue. It sits about 2 degrees west of Gamma Cygni and 2 degrees north of the Crescent nebula, and maybe for this reason it doesn’t have many “individual” images on Astrobin. The region immediately surrounding this cold knot of interstellar medium is, however, very interesting, with emission nebulae and filaments glowing in all the three wavelengths typically captured by narrowband imagers. This image is a rendering in the Hubble palette of SHO data.

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.
