| NGC2440 in the constellation Puppis is one of the featured planetaries in my gallery of 'Planetaries Of The Week'. Find out more about this spectacular PNe on that page! |
NGC4361 lies in the constellation Corvus and is also featured in 'Planetaries Of The Week'. The Hubble Space Telescope has provided both of these wonderful images. |

| NGC7662, the Blue Snowball is a very visible PNe in the constellation Andromeda. The colors in these images are due to imaging with filters optimized for wavelengths of Nitrogen, Oxygen, and Helium. The angular size of this PNe is 16 arcseconds.It is estimated to be 3,500 light years distant. |
NGC6781, a rather large and somewhat faint PNe in the constellation Aquila, has an angular size of just around 106 arcseconds. The distance to this planetary is estimated to be 2,600 light-years. All the images in this panel were taken by Dr. Bruce Balick using the 2.1 meter telescope at the Kitt Peak National Obs. |
NGC2610, an even fainter PNe in the constellation Hydra is classified as a 'ring' nebula. A more well known ring nebula is known as 'M57' in the constellation Lyra. The distance to M57 is about 2,000 ly and the distance to NGC2610 is 5,500 ly. The magnitudes of each are 9.7 (M57) & 13.6 for N2610. |
