Planetary Nebulae Images6

**Hubble Space Telescope Images of Southern & Northern Skies Planetaries**

NGC2867, another 'ring' type planetary, resides in the southern constellation of Carina, and is majestically rendered in this Hubble Space Telescope image. The white dwarf central star shines at mag. 16.6 and the PNe's distance is 5,500 ly. It's angular size is about 14 arcseconds.	NGC6826, in Cygnus, is commonly named The Blinking Planetary. Astronomers have noted that with this PNe in the center of the eyepiece field, switching from direct vision to 'averted' vision, the planetary appears to disappear and appear, thus providing a blinking effect. The angular size of this planetary is about 26 arcseconds, distance 2,200 ly.

**Anglo-Australian Observatory Images Of Two Unique Planetary Nebulae**

NGC1360 in Fornax, a large, somewhat faint planetary nebula with a binary pair central star (not visible here) is the subject of many research papers on this type of PNe. The angular size is 460" x 320" (arcseconds), and the magnitude roughly 9.6. However, due to its extended size, the estimated 'surface brightness' value is 13.6, making it a difficult object for smaller telescopes.	NGC5189 in the deep southern constellation of Musca (The Fly) is obviously not your run-of-the-mill planetary. It is classified as a type 5 (Irregular) and in this image, there are wispy envelopes of gas, knots of both hot and cool expansions and a very concentrated central bar of stellar debris. The central star of this PNe shines at about 14.9, and the size of the nebula is about 160", although visually, the most prominent feature of the nebula is the central bar running northeast to southwest.
