8" f/6, 150x + UHC, Bortle 4, SQM-L 21.2
Pretty faint, small, round, evenly bright.

MODERATE

12.5" f/4.5, 111x + UHC, SQM-L 21.3
bei 111x und UHC wird der PN indirekt als kleine Aufhellung sichtbar und kann länger gehalten werden - der Südwesten scheint etwas heller zu leuchten - [OIII] hat bei keiner Vergrößerung geholfen

Abell 3 (PN)

../images/dss/dss2red_021206.67_+640902.20_5_web.jpg
Image source: DSS II (red) - 5'×5'
Name: Abell 3, PK131+2.1

8" f/6, 150x + UHC, Bortle 4-, SQM-L 20.8
At 80x there was one, at 150x two faint stars visible east of the nebula. The nebula itself wasn't seen.
FAILED

Abell 82 (PN)

../images/dss/dss2blue_234547.75_+570358.50_5_web.jpg
Image source: DSS II (blue) - 5'×5'
Name: Abell 82, PK114-4.1
Type: PN
Constellation: Cas
Coordinates: 23h45m47.75s / +57°03'58.50"
Brightness / Size: 15m.2 / 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.

EASY

12.5" f/4.5, 72x + UHC, SQM-L 21.3
bei 72x sowie UHC ist der PN schwach auszumachen - leicht helleres Zentrum - [OIII] hilft auch - bei 160x und UHC ist nach Osten versetzt ein Stern wahrnehmbar
MODERATE

Abell 84 (PN)

../images/dss/dss2red_234744.02_+512356.90_5_web.jpg
Image source: DSS II (red) - 5'×5'
Name: Abell 84, PK112-10.1

Constellation: Cas
Coordinates: 23h47m44.02s / +51°23'56.90"

8" f/6, 80x + [OIII], Bortle 3, SQM-L 21.3
Round, pretty large, evenly bright. Bright star within (?) the nebula.

MODERATE
René Merting
12.5" f/4.5, 144x + [OIII], SQM-L 21.3
bei 144x und [OIII] zeigt sich der PN indirekt als diffuse schwache Aufhellung östlich von einem helleren Stern - weitere Vergrößerungen und auch UHC probiert, aber keine bessere Sichtbarkeit erzielt - schwer
MODERATE
