Object Information Imaging Details |
||
When a star of less than a few solar masses depletes its hydrogen and helium nuclear fuel, the core collapses into a white dwarf and the outer layers are blown away in a series of layers. Light from the dwarf star ioninizes and illuminates the expanding gas cloud creating what is known as a planetary nebula. The Dumbbell Nebula is one of the closest (1000 l-y) and brightest (mag. 7.5) planetary nebulae. It is a beautiful object to observe visually through a modest aperture telescope. This object was imaged at City of Rocks State Park during the Fall 2006 Southern New Mexico Star Party. The sky was cloudless with moderate seeing.
