Looks a bit like a nuclear explosion to me....
From
GalaxyMap:Sh 2-37 lies in the direction of the ionising star cluster
Dias 5. It is also known as IC 1283/1284 and the powerful radio source
W 34.
Sh 2-35 and Sh 2-37 are associated with a 130 thousand solar mass giant molecular cloud and appear to be part of the Sgr OB7 association. Sh 2-37 is visible through a hole in this molecular cloud. This is a very active star formation region.You can find an infrared image of part of this region here, full colour images here and here, and an analysis of the correct names for these objects here.
GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>
There are 313 Sh2 objects.
As of the date when this image was posted:
I had imaged 278 (88%).
There are 12 too diffuse/large to image with my set up (Sh2 111, 117, 122, 131, 132, 145, 178, 218, 221, 230, 268 and 310). I may look for other images so I can get a complete collection or make my best shot for completeness.
There are 5 that are never above 14 DEG (Sh2 2-6) [Edit 7/12/21- I can get these now with pier upgrades and the images are completed as best as I can].
These remainder are in Expert Scheduler waiting for them to pass by.
The first one was taken on December 23, 2013.
Many were taken with my old Tak 180 ED, which had a wide field of view, but was replaced with my Stellarvue 130, which is more narrow field. I have also taken two very wide field HA images with my Nikon D800 and a 50mm lens.
This is my collection:
