B 18x70, SQM-L 21.5
an der Stelle, wo B 34 stehen soll laut Sternkarte, blinken nur drei bis vier ganz schwache Lichtpünktchen im südwestlichen Teil der rund wirkenden Nebels hervor - die Abgrenzung zum Sternumfeld fällt nicht sehr schwer - an den Rändern gibt es einige hellere Sterne und beim Schwenken sehe ich deutlich, dass die Gegend sich vom restlichen Umfeld unterscheidet bzw. leicht dunkler wirkt

EASY
12.5" f/4.5, 45x, SQM-L 21.5
bei 45x fällt eine größere Fläche mit weniger Sternreichtum auf, durch die sich eine gezackte Kette schwacher Sterne Nordsüdwärts zieht - markant ist der Nebel aber nicht, sondern nur bei Wissen um die Bedeutung erahnbar - am eindeutigsten ist der südliche Teil erkennbar, der sich in einem geschwungenen Bogen etwas mehr vom Sternumfeld abgrenzt, sonst ist aber keine echte Begrenzung auszumachen - vielleicht sind 12" schon zuviel Öffnung und es werden innerhalb des Nebels zu viele Sterne sichtbar

At 22x, the components A, B and CD are immediately conspicuous, where A dominates. They form a beautiful, acute-angled triangle. At 69x, color differences are also visible. A: subtle orange; B: grey-bluish; CD: tendency to orange. Rewarding, because the double stars STF 928 & STF 929 as well as the very conspicuous carbon star UU Aur are in close proximity and can partly be observed together in one field of view!

At 57x nothing seen at first sight. At 133x the much fainter component was visible after a short time as a tiny star in the correct position angle. With this knowledge, the observation at 57x was also successful, even if one has to look very closely. The challenge here is not so much the angular distance as the large difference in brightness.

Image source: DSS II (blue) - 5×5'
Name: UGC3327, MCG+05-14-001
Type: BN, RN
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.
