Orion
from Happy Jack with the 10D
Constellation
in Western sky
Uploaded 3/20/05
Despite the total
lack of hydrogen alpha sensitivity in this camera, dark skies
seem to be able to make up for at least some of this deficiency
in wide field astrophotos. The entire constellation is shown
here, with the "reds" more of a magenta color representing
the hydrogen clouds. You can clearly see the arc know as Barnards
Loop circling the belt stars, the huge Lambda Orionis bubble
near the top, and the Rosette nebula to the upper left. The Horsehead
nebula and Flame nebula are also seen on the left belt star.
The constellation was setting in the west, and some trees can
be seen on the lower right.
The camera leaves most
stars bluish in color, and the sky is as neutral as I could get
it.
