From Galaxymap:
Sh 2-283 includes the infrared cluster [BDS2003] 84 and according to Avedisova is ionised by an uncatalogued B0 V class star (MFJ Sh 2-283 8).
Russeil concludes the Sh 2-283 to Sh 2-286 are all part of one star formation region located in the Milky Way's Cygnus (Outer) arm. These nebulae are described in detail in the description of the Monoceros Arc (220° - 210°) sector in the Commentary on the Galactic Plane.
Includes the infrared cluster [BDS2003] 84. [1]
Sh 2-283 to Sh 2-286 are all part of one star formation region. [2]

GENERAL NOTE ON SHARPLESS2 OBJECTS>>>>>>>>>>>>>
I have been on a project for several years now to image all the Sharpless2 Objects that I can see from my location near San Francisco. I chose these because they are visible in light polluted areas. These objects generally represent left over Hydrogen along the edge of the Milky Way that has gotten molded into interesting shapes.
There are 313 Sh2 objects and those below 70 and above 283 are generally too low on the horizon for me to image... this leaves me 213 that are feasible... and I have imaged all of these but 36. 13 of these are too big for my system. 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.
This is my collection:

Hope you enjoy these obscure but interesting objects...
