At 56x with [OIII] filter round, evenly bright. At 100x with [OIII] filter barely visible with direct vision, shape hardly perceptible. A star (central star?) was seen within the nebula. At 100x with UHC filter the nebula appeared pretty faint.

120mm f/5, 40x + [OIII], Bortle 4, SQM-L 21.0
Rather faint & small, roundish with fading edges (?). At 75x with UHC filter also quite well visible with averted vision. Not visible without any filter.

Abell 82 (PN)

DSS

Name: Abell 82, PK114-4.1
Type: PN
Constellation: Cas
Coordinates: 23h45m47.75s / +57°03'58.50"
Brightness / Size: v15.2 mag / 1.5x1.5'
120mm f/5, 75x + UHC, Bortle 4, SQM-L 21.0
Oval, very faint with embedded star. Located southeast of a medium bright star.

MODERATE
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.
