Object description:
The small open star cluster NGC 6383 in the
right half of the image is a real treasure in the sky. Its S - shaped star
chain and the central bright star are striking. The distance to the cluster is
about 3200 light years and the age of it is 9 million years. Not so noticeable
is the open cluster in the left half, Trumpler 28. With 4400 light-years, it is
further away from us than NGC 6383 and with 20 million years it is also as
twice as old. The two larger images show a mosaic with the adjacent cluster
M 6.
