I think this representation of the data displays an old very dim SNR shock wave in a Hydrogen cloud. This is Super Nova Remnant G065.3_05.7 to the west of the veil nebula very close to the border of Lyra. This image is centered at RA=19h 33m 36s and DEC= '+31deg 12' 02". Parts of this SNR have designations in the Sharpless catalog with identifiers Sh2-91, Sh2-94, Sh2-96. This object is large at roughly 4degX5deg. The image is a single field of view with multiple sub-frames taken over several nights during the months of May thru July 2015. All imaging was done by remote control. Color is mapped OIII, HAlpha and SII narrow band...
