Corona Borealis, the Northern Crown, is a lovely semicircle of
stars centered in the picture and opening to the left. Alphecca,
or Gemma, is the bright star at the Crown's center directly
in the middle of the picture. Curving up and to the left are
Nusakan (Beta) and Theta, while down and to the left are Gamma,
Delta, and Epsilon. The strange carbon star R Coronae
Borealis, which occasionally disappears from naked eye view after
covering itself in carbon soot, is to the left and just slightly
down from Alphecca. Nu (Nu-1 and Nu-2) is at far left center; Sigma
is just up and to the right of Nu.
Bootes is at the top of the
picture, Serpens Caput
at the lower right, Hercules at lower left.
The faint vertical red and green bands in the background are from a weak
northern lights display.
North is toward the upper left.
