The Eagle Nebula
JAN 20, 2011
The Eagle Nebula is one of the iconic objects of the night sky made famous
by the Hubble Space Telescope. But, how many realize that it is not a small
object? The field of view in the image shown here is about half a
Moon-diameter in wide and a little less than that in height. The nebula
is an emission nebula. It shines brightly in so-called Hydrogen-alpha
light, which is a very deep red color near the edge of the range of visible
light detectable by human vision. But, it is fairly easy to take nice
photographs of this object. The image shown here was taken by me with my
10 inch reflecting telescope. Total exposure time was two hours.
