NGC 6559
& (IC1274/ 1275/ 4685) |
|
Info |
NGC 6559 & IC companion
nebulas are located in the
constellation of Sagittarius. It is probably associated with the better
known M8 & M20 nebula complex, but separated by dark dust lanes. The over
all red hue is due to glowing hydrogen gas energised by the radiation of
hot young stars, know as emission nebula. The blue regions
are from dust reflected starlight,
know as reflection nebula.
Dust is also
evident by the many odd shaped dark lanes and isolated patches. It is
approximately 5,000 L.y. away. |

quite poor and had bloat in the green channel due to
high transparent cloud. Image reduced to 85% of
