120mm f/5, 75x + UHC, Bortle 4, SQM-L 21.0
Conditions in the target region: SQM-L 20.6
Observation very marginal. At 75x with UHC filter I glimpsed a round, even haze, but unsure retrospectively.

FAILED
152mm f/5.9, 34x + [OIII], Bortle 3-, SQM-L 21.3
Roundish, evenly bright. Well visible with averted vision, but not conspicuous.

MODERATE
8" f/6, 37x + [OIII], Bortle 4, SQM-L 21.2
Conditions in the target region: SQM-L 20.9
Rather faint and less evident, relatively large, round, evenly bright. At 80x with UHC filter similar, with [OIII] filter even a bit fainter.

MODERATE

12.5" f/4.5, 72x + [OIII], SQM-L 21.5
bei 45x und [OIII] zeigt sich der PN schwach und keine echten Konturen - bei 72x und [OIII] ist der PN indirekt rund abgegrenzt sichtbar - gefühlt ist das ein PN, der herausgearbeitet werden muss, denn je länger man das Objekt betrachtet, desto besser wird die Ansicht
MODERATE
