Sharpless 115 and 116

I’ve been sitting on a mountain of data for months and haven’t had time to process anything. Ugh! Finally got to sit down and process something. This is Sharpless 115 and 116 processed in PI and PS - an approximate 2/3 crop. The SII signal was strong enough that I was able to differentially process much of it from the Ha and show the spacial distribution of these well. The seeing was not great but I’m happy with how this came out. Version B is a revision to dampen the stars a bit.

Sharpless 115 is a large molecular cloud in the direction of Cygnus approximately 7500 light years distant. The primary part of this target in the upper right of the image is a nebula sculpted by the stellar winds of several newborn star clusters including Berkley 90, an open cluster near the lower right of the region. The extended Ha region below is also part of SH2-115. The little gem in the lower left is SH2-116, once thought to be a planetary nebula owing to its shape and structure, however evidence indicates that this is an Ha nebula, a smaller star forming region with typical distributions of central ionized oxygen and peripheral Ha.

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.
