| NOTES |
: |
this bunch of Ha and dust and dark stuff is very faint, located between M17 and M18, just to the east...It is about 40 arc minutes across, but I can't determine edges... it sort of blends into the clouds. This was very difficult to process... A tiny piece of M17 is in the upper left corner, and most of M18 lower left.. |
