Our 9th deep sky target, imaged by the French AstroDarkTeam composed of Stephane Rolland and Pascal Gouraud from the beautiful and efficient Astro ARO remote observatory in Portugal.
Noted in the 1959 catalog by astronomer Stewart Sharpless, Sh2-115 is a faint emission nebula.Sharpless 115 is located just north and west of Deneb, the alpha star of the constellation Cygnus. This emission nebula lies along the edge of one of the outer Milky Way's giant molecular clouds, about 7,500 light-years away. Hot stars in star cluster Berkeley 90 power the nebular glow. The cluster stars are likely only 100 million years old.

The small blue object, is Abell 71. This nebula is also cataloged as PK 085+04.1, PN G084.9+04.4 or Sh 2-116. Initially cataloged as a planetary nebula, the object is now recognized as a small patch of HII emission.

Technical details
Total exposure of 67 hours and 45 minutes have been integrated between April 25th and June 27th .24,5 hours for HA, 19,75 hours for OIII and 21,5 hours for SII allows us to obtain this image which offering a wide palette of colors, contrast and details.
For stars, we integrated 2 hours with RGB filters

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.
