Sh2-115 and 116 (HOO)

This image shows the emission nebula Sh2-115 (also known as LBN 357) and the planetary nebula Sh2-116 (also known as DWB 118 and Abell 71). This image field is in the Cygnus -X region which is the area of the DWB catalog. This image contains ten objects of the DWB catalog. This image field also contains four LBN objects (the afore mentioned LBN 377, LBN 352, 358, and 362). The open cluster Berkeley 90 is also in this image field. One of the members of Berkeley 90 (TYC 3573-1489-1) is the ionizing star of Sh2-115 - it is estimated to be about 9630 light years distant (by paralax). So Sh2-115 is in this range for distance. These objects and some of the brighter stars are identified in the annotated image.

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.
