Revision title: The interesting part of Sh2-310

I almost wrote the most famous intro by Gary: This Astrobin-Debut Object is ... , but I knew that Jerry finished his complete Sharpless catalog, so it could not have been. Searching for Sh2-310 does show some images, but none of them were actually showing the nebula the way I captured it. But ... I do understand why this is so, there is really nothing dramatic in this nebula. I chose this target since it was one of the objects that I could squeeze into my main target sequences, and I always try to use every second of clear skies. And with such a low declination, there is not a lot of imaging time for me with my restricted views.
All in all though I thought it was a very interesting target since I had no reference, which was something new for me, did not know what to expect. In aftermath, I should have taken RGB images with an Hα addition only, I believe this would have popped the nebula in a better way. There is almost ... no no ... there is no OIII visible (at least with my setup) and just a little bit of SII.
Version A shows the wide field image, while Version B shows the most interesting part of Sh2-310.
Enjoy the holiday season and stay safe!

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.
