PNG 015.5+02.8 is a faint 9 arcminute planetary nebula in Serpens at the center of this image. It has no detectable OIII emission.
Sharpless 2-46 is the large bright nebula to the right of the image. It is around half the angular width as the moon and is around 2,000 light years from Earth. It is ionised by the bright supergiant star HD 1165319. The star has created a Bow Shock to its right which also contains OIII emission.
Close to the left hand edge of the image is planetary nebula StDr 31 which was recently discovered by my good friends @Marcel Drechsler and @Xavier Strottner.
This was a joint project with the Astronomical Society of Edinburgh who provided additional H-alpha data for PNG 015.5+02.8 using their ASE Remote Observatory at Trevinca Skies in Spain.

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.
