Using Wei's shared Lulin data. 
Well, I did this before twice as part of Sh2 84 and saw nothing, but I did have a good write up... the O-III is amazing and seems to identify the structure in the write up. Neither 8 years ago with my Take 180ED nor 4 years ago with my Stellarvue 130 used O-III (A mistake now it seems).
Sh2 84 HA RGB 
Sh2 84 H-alpha This is a plate solve of the current image (either you get the plate solve or two images) so Sh2 84 can be identified:
WR 128 Lulin Observatory Data Test Plate Solve From Galaxymap:This HII region, also called LBN 131, is near in the sky to the Wolf-Rayet star WR 128. Both Sharpless and Avedisova list WR 128 as an ionising star. However, there is some controversy about whether Sh 2-84 is part of the ring nebula surrounding this star or lies at another distance.
A look at this region in hydrogen-alpha reveals that although WR 128 lies in this direction, Sh 2-84 appears to be the brightest part of an enormous ring of ionised gas that is not centred on WR 128 but may instead surround the O7.5 I supergiant QZ Sge. Given the size of the ring it may be much closer than the Wolf-Rayet star.
It also seems possible that both QZ Sge and WR 128 contribute to the nebulosity seen in this direction and so Sh 2-84 is not a single object.
3DLUT Technique for Color Management/Enhancement.For those who have been following the saga of 3DLUT learning. This is the utilization of the CL Panel to specifically increase saturation in the blue parts of the nebula (Panel H compare with original F).
