Object(s): NGC 7026
Category: Planetary nebula.
Class: 3a
Constellation: Cygnus
Data: mag 12.7(p) size 20" central star mag 14.2
Position: RA 21h:06m 18.5s DEC +47:51'08"
Description:
This planetary was easily found just 12.5' north of 4.6 mag. star 63 Cyg. The
pn was blue/gray and the central star was not seen. Megastar lists the central
star at a fairly bright mag. 14.2. Maybe it is obscured by dust or the bright
inner region of the nebula? The overall shape of the nebula was rectangular,
aligned roughly north/south. A prominent dark lane ran down the middle
dividing the nebula into two almost equal segments. The central part of each
section was much brighter than the ends with the central section of the eastern
segment appearing to be shifted slightly to the north. The bright section of
the eastern segment also appeared to be very slightly shorter than its western
counterpart. The east and west borders were very sharp and distinct but the
north and south ends gradually faded away into the background sky glow.
Inserting the orion uldtrablock caused the north and south ends to grow
slightly in lenght. The filter also revealed a very faint extension to the
southeast from the south end of the eastern segment. I could hold this
extension more than 50% of the time with averted vision but wouldn't bet my
life that it is actually there.
