Sharpless 2-115 in Cygnus

Link: https://stevemilne.smugmug.com/Photos/Sky/Nebulae/

Sharpless 115 is a faint emission nebula around 7,500 light years away in the constellation of Cygnus. The nebula is ionized by stars in the open cluster Berkeley 90 (from the Berkeley Open Cluster Catalogue, 1958). The cluster, which is embedded in Sh 115, is thought to be only 100 million years old.

To the left of centre, just below the midline, is the planetary nebula Abell 71. I have been unable to find any distance estimates for Abell 71.

Sharpless 115 was photographed between 30 August and 24 September 2019 from a remote imaging rig that is jointly owned and operated by Barry Wilson and me.

Capture details are as follows:

Telescope: Takahashi FSQ 106

Camera: QSI 683 WSG

Filters: Astrodon 5nm NB

Mount: 10 Micron GM1000HPS

SII: 20 x 1200s

Ha: 22 x 1200s

OIII: 21 x 1200s

A total of 21 hours exposure.

Data: Steve Milne & Barry Wilson

Processing: Steve Milne

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.
