16" f/4.5, 100x + [OIII], Bortle 4, SQM-L 21.0
At 56x with [OIII] filter the nebula appeared southeast of the medium bright star as a slightly elongated brightening. I think this originates from the faint NE and SW edge. At 100x the northwestern edge was more defined, the southeastern edge fades more into the background. It looked a bit fan-shaped. A star was visible within the nebula.
