Out of all of the photos I took that night, this was the only one I was happy with, and this was not even an attempt to get a photo, it was instead pure curiosity as to see if there was much in the sky that I could not actually see.
Intense light streams from Rigel (bright star at right) across 40 light years of space to illuminate the Witch Head Nebula, then reflects another 775 light years to reach us. This nebula is very dim and is just barely above sky glow at a clear dark site. South is up in this image.
Rigel is B8 supergiant star with an absolute visual magnitude 40,000 times that of our Sun. Its surface temperature is 11,000 K.
