Category: Planetary nebula.
Class: smooth disk w. traces of ring structure
Constellation: Monoceros
Data: mag ?  size 34"
Position: RA 07:00  DEC +14:37
Description:
Pinned down position with DSS print.
At this position a 13-14 mag star and some fainter next to it.
With 9 mm Nagler (280x) + OIII the faint stars disappear almost completely,
but instead there appears a haloshaped nebular around the brighter star.
Exactly round, not easy, only whith averted vision.
I am quite sure, that this is not just straylight from the star due to the filter.

I also tried the galaxy UGC 3621 in the neigborhood: Faint extended glow.
