Abell 82 (PN)

DSS
© DSS II (blue) - 5×5'
Name: Abell 82, PK114-4.1
Type: PN
Constellation: Cas
Coordinates: 23h45m47.75s / +57°03'58.5"
Brightness / Size: v15.2 mag / 1.5×1.5'
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.

Brightness / Size: v12.0 mag / 0.75×0.75'

Name: IC1747, PK130+1.1
Type: PN
Constellation: Cas
Coordinates: 01h57m35.73s / +63°19'18.3"
Brightness / Size: v12.0 mag / 0.3×0.3'
80mm f/6.25, 50x, Bortle 6-, NELM 5.0+, SQM-L 19.6

DIFFICULT
4.5" f/8, 90x, Bortle 6-, NELM 5.0+, SQM-L 19.6
Quite compact, round, extended, evenly bright. Well seen with averted vision.

MODERATE
8" f/6, 96x, Bortle 4, SQM-L 20.9
At 96x fairly small, evenly bright nebula, evident with averted vision. At 171x obviously extended and visible with direct vision.

PK128-4.1 (PN)

DSS
© DSS II (red) - 10×10'
Name: PK128-4.1, Sh2-188, LBN633
Type: PN
Constellation: Cas
Coordinates: 01h30m33.11s / +58°24'50.7"
Brightness / Size: - / 10.0×3.0'
8" f/6, 37x + [OIII], Bortle 4
Only tried short. However the eyepiece gets constantly wet with dew and the conditions get worse due to upcoming fog.
