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

Coordinates: 05h36m40.90s / +31°51'16.00"
Brightness / Size: b13.0 mag / 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!?).

8" f/6, 150x, Bortle 4
Relatively bright central star, surrounded by an apparent halo, which gets darker towards the edges. Well visible with averted vision.
