Seen as an evident brightening with a dark notch. Looks like a 'V'. Without any filter I saw nothing.

mit 2x HBeta vor den Objektiven ist eine kompakte, diffuse Aufhellung erkennbar, indirekt ist der Nebel sehr auffällig

EASY
B 10x50, UHC, SQM-L 21.5
mit 2x UHC vor den Objektiven ist der Nebel einfach und besser als mit HBeta erkennbar, hell und deutlich, jetzt sind auch mehr Details erkennbar, IC 410 wirkt nach Osten ausgebeulter und nach Westen ein wenig eingedellt und etwas besser begrenzt

EASY
12.5" f/4.5, 72x + UHC, SQM-L 21.5
bei 45x und UHC schmiegt sich eine helle Nebelsichel von Osten über Norden nach Westen um den Sternhaufen NGC 1893, nach Nordwesten ist eine weitere leicht zerfranste Ausbuchtung erkennbar - bei 72x und UHC ist die Sichel ausgeprägter und zieht sich bis Südwesten

UGC 3327 (BN)

Constellation: Aur
Coordinates: 05h36m40.90s / +31°51'16.00"
Brightness / Size: b13m0 / 2.5x2.5'
Quite interesting object, which is listed as a galaxy in the UGC/MCG, whereas in Simbad it is a reflection nebula. However to me it appears visually more as a reflection nebula due to the bright, stellar center (central star!?).

Relatively bright central star, surrounded by an apparent halo, which gets darker towards the edges. Well visible with averted vision.
