Object(s): Abell 30 (PK 208+33.1), IC 2398, IC 2406
Category: Planetary nebula. External galaxy.
Class: Smooth disc w. traces of ring structure
Constellation: Cancer
Data: mag 15v5  size 109"
Position: RA 08:47  DEC +17:53
Found position with DSSII blue printout.
It took me some time to find this PN, but once spotted it stayed
there (15 mm Panoptic, 168x + OIII).
Central star of approx. 14 mag surrounded by a large diffuse glow,
with very diffuse edge. I can't really say, where the edge is, it
depends on how far indirect I look at.
Two Galaxies lie in the neighborhood:
IC 2398 at 8' south of A30. With 7 mm Nagler (360x): small, fairly
faint, but easily directly visible. Oval, elongated N-S.
IC 2406 at 21' SE of the planetary immediately seen in the 32 mm WF
(79x), brither and larger as the above. In the 7 mm Nagler (360x)
elongated blob with slightly squared central part.
