Once I really started getting into observing, many years ago, I found that I really liked looking at planetary nebula. I almost made this a list of planetary nebula and nothing else but I could not do that, there are just to many galaxies that I also enjoy observing, so I have included some winter galaxies for us to observe. Here are some very interesting objects to observe this winter. Remember to try higher magnifications and a OIII filter on these planetary nebula. I hope you enjoy them as much as I do.
1. NGC 1501, A planetary nebula in Camelopardalis, the Blue Oyster Nebula. A light blue mottled disc that appears annular at high magnification.
2. NGC 1514, A planetary nebula in Taurus, the Crystal Ball Nebula. A faint mist around a bright central star. The disk will be best seen with a OIII filter.
3. NGC 1532/1531, A galaxy pair in Eridanus. A large edge on interacting galaxy with a small faint companion galaxy.
4. NGC 1535, A planetary nebula in Eridanus, Cleopatra’s Eye Nebula. A bluish disk with visible structure.
5. NGC 1721, 1723, 1728, A galaxy Trio in Eridanus. A tight grouping of three small faint galaxies located 8′ south of the galaxy NGC 1725.
6. NGC 2024, A bright nebula in Orion, the Flame Nebula. A large bright nebula just east of zeta Orion that has a large branching dark nebula through the middle of the nebula.
7. IC 2149, A planetary nebula in Auriga. It appears stellar at low magnification but shows a small light blue disk at high magnification.
8. IC 443, A super nova remnant in Gemini. A small seldom viewed nebula that can be seen using a UHC or OIII filter in an 8-inch telescope from a dark sky site.
9. NGC 2683, A galaxy in Lynx, the UFO Galaxy. This is a large bright almost edge on galaxy that can be seen from a dark sky site in 10×50 binoculars.
10. NGC 2392, A planetary nebula in Gemini, the Eskimo Nebula. On nights of good seeing with high magnification, there is a lot of detail to be seen with a conspicuous central star.
