Here we see a very complex
field in the constellation of Cygnus, the Swan. The pink and
red wisps all over the field is hydrogen gas blown into bubbles
by the hot blue stars in the neighborhood. And as a bonus, the
blueish ring you can see faintly here is the remains of a star
which exploded in a Supernova tens of thousands of years ago.
This is a 4 hour exposure from Happy Jack with an 11 inch telescope.
Cygnus Super Bubble
Arcs SNR: G65.3+5.7
One of the most exciting
fields of nebulosity in Cygnus is the "Cygnus SuperBubble
Complex. These arcs of hydrogen nebulosity are parts of a huge
complex of bubbles blown in the molecular clouds here by numerous
hot blue stars. As an added bonus, the big blueish ring is the
supernova remnant G65.3+5.7 and while faint, has some incredibly
fine details. I must add that it was a pretty dark and transparent
night considering all the fire smoke that has been plagueing
us lately, with a zenithal SQM of 21.8.
