Sh2-216, Dean Salman
Second closest planetary to earth
taken using Epsilon 160 F/3.3 astrograph using the SBIG STL-6303
XE CCD Camera. I had
to use a hydrogen-alpha filter otherwise this kind of detail
would not be possible in the 9 hours of exposure time. This
image is by far the most published image in a number of books
and was one of the four images published in Sky and Telescope's
Beautiful Universe 2008.
