SH2-115 in SHO

This image of SH2-115 also includes the planetary nebula SH2-116. It was captured as part of the monthly imaging challenge at Cloudy Nights.

There is over 40 hours of total integration time across the narrowband filters and the broadband RGB that was used to create more natural looking stars. Even with my relatively dark Bortle 2-3 skies the individual subs of SII and OIII are very dim showing little of the underling nebulosity. I continued capturing data until I thought SNR was sufficient to process appropriately

The main tool to stretch and balance the dimer SII and OIII was Generalized Hyperbolic Stretch in PixInsight. Several stretches were done with special stretches of just the Red and Blue channels. Of course other tools like BlurXTerminator and StartXTerminator were also used.

I appreciate any and all comments and of course your thumbs up if you like this interpretation of this target.

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.
