Hello Robin,
I have only one sighting of the VMT-10 (SNR 206.5 -00.1): A wide streak pointing north, extension longer than in IDSA p.60
6" F/5 achro, EPs: Leica HC Plan S f=25mm, Leica L f=32mm, H-Beta (12nm), OIII (10nm)
Backyard (nominally Bortle 4), 30th March, 2019
Other objects observed on that night: Sh2-308 (W-R)
The VMT-10 has been pretty time consuming, and without having seen before the astrophoto you have linked, it can be easily overseen.
Thank you for introducing this object,
JG
