As in the previous three seasonal lists, there are planetaries here to amaze you, and
to challenge your observing skills to the limit. There are at least four planetaries in
which one should be able to discern color in the nebulosity, and four in which the central
star should be visible. And look !, all but four are located in the Northern Hemisphere,
and only one is placed at a moderately southern declination (IC 5148/5150). How
about locating a planetary mixed in with a globular cluster? If you can observe Pease 1 in
M15, congratulatons! A finder chart for this one is included as a link from this
page. Be sure to send in any observation reports!
You can send them to snyder@ix.netcom.com
and Thank You! (Continued)
The twenty five objects in this list appear in the Fall skies, and range in Right
Ascension from 21h to 03h. The showcase objects are the Saturn Nebula, the Blue
Snowball, and M76, the Little Dumbbell. The largest planetary nebula, but definitely
not the brightest, NGC 7293, the Helix Nebula will be a challenge to most, and be sure to
take along your nebula filters (Filters OIII, UHC at least)
because you'll be needing them with this group. A couple of the most challenging
objects are Pease 1 and Jones 1 in Pegasus, and I've also thrown in a couple of the Abell
PN's to make things interesting.
PLANETARIES WITH OBSERVABLE CENTRAL STARS
NGC 7009 (Saturn Nebula): With a fairly high surface brightness of around 7
magnitudes/sq. arcminute, and its moderately small size, this greenish-blue oval of a sky
gem sports a magnitude 11.9 central star. This should be visible in a 6"
telescope, but can be difficult due to the surface brightness.
NGC 7027: Various sources I have encountered place the magnitude of the central star anywhere from 11.3 (Blue sensitive) to 16.2 to 'has never been observed'. So take a look for this central star and let me know. I'll be looking for it too.
NGC 7293 (Helix Nebula): A prominent central star with a magnitude of 13.4 and should be visible in a 6".
NGC 40: In Cepheus, this moderately sized and uniformly bright PN has a easily visible central star. The magnitude is 11.5 and with a spectrum type of WC8, it has bright emission lines and presents a 'beaded' appearance when seen through a prism.
NGC 246: An 11.8 magnitude central star, which should not be too difficult.
Since the surface brightness of the PN is quite low, the star should be prominent.
