NGC869/884
The Double Cluster
Dual
Clusters in Perseus
Uploaded 11/9/04
There
are few objects in the sky as exciting as the dual rich open
clusters, known as the Double Cluster in Perseus. In both binoculars
and telescope, they stir the intellect into contemplations of
cosmic wonder. Besides being very rich, a sprinkling of very
orange stars lies over this group, making for a dramatic portrait.
This image is a pair of 5 minute exposures stacked in Picture
Window Pro, using multiply - this is the same as stacking two
negatives in the enlarger. I cant emphasize enough how having
the larger field of view is appreciated over the usual ST8i shots. |
