152mm f/8, 92x + [OIII], Bortle 4, SQM-L 21.1
Only a short attempt without an detailed finder chart. I used 66x, 92x and 133x each with [OIII] filter.

120mm f/5, 40x + [OIII], Bortle 4, SQM-L 21.1
Conditions in the target region: SQM-L 20.3
At 40x without filter just a faint, roundish brightening with averted vision. At 75x without filter well visible with averted vision. At 40x with [OIII] filter the nebula appears bright, round, evenly bright and is visible with direct vision.

152mm f/8, 30x + [OIII], Bortle 4, SQM-L 21.1
Without filter the nebula is visible only as a faint brightening. With [OIII] filter the nebula becomes very prominent. Round, uniformly bright, relatively large.

8" f/6, 171x, Bortle 4+, NELM 6m.0+, SQM-L 21.1
Conditions in the target region: NELM 5m0+, SQM-L 20.2
At 37x visible with averted vision as rather faint, round, small nebula. At 100x evident, round, evenly bright. At 100x with [OIII] filter partly lemon-shaped, center appeared somewhat darker (ring), well perceptible with direct vision. Beautifully embedded in the prominent, star rich cluster M46!

100mm f/6.4, 49x + [OIII], SQM-L 21.3
Conditions in the target region: SQM-L 20.5
bei 49x sowie UHC wird der PN deutlich als nebliger Fleck im Norden von M 46 sichtbar - indirekt noch deutlicher mit homogener Helligkeit - mit [OIII] etwas mehr Kontrast

8" f/4, 85x + [OIII], SQM-L 21.3
bei 40x ist der PN schon ohne Filter als schwacher Schimmer nördlich einer V-förmigen Sternkette wahrnehmbar - bei 85x und [OIII] ist der PN dann sehr auffällig und schön rund - indirekt werden zwei Sterne sichtbar - selbst ohne [OIII] bleibt der Nebel auffällig - die Kombination aus den drei Objekten M 47 + M 46 + PN taugt aus meiner Sicht zum Höhepunkt der Beobachtungsnacht

120mm f/5, 40x, Bortle 4, SQM-L 21.0
Conditions in the target region: SQM-L 20.0
At 18x stellar and well visible with averted vision, at 40x without filter almost stellar. At 40x with [OIII] filter non-stellar, but still very compact. At 75x the nebula appeared as very small, round, evenly bright disc.

100mm f/6.4, 160x, SQM-L 21.3
Conditions in the target region: SQM-L 20.0
bei 38x ist der PN als winziger fast stellarer Nebel auszumachen - bei 49x ist indirekt ein helles Zentrum zu sehen, direkt ist der Nebel gleichmäßig hell - Nebelfilter sind ohne verbessernde Wirkung - der PN hat Vergrößerungen bis 160x gut vertragen
