Brian Paczkowski: Dolphin Head Nebula (Sh2-308) in the constellation Canis Major. This bubble-like nebula surrounds a Wolf-Rayet star EZ Canis Major. The visual magnitude is 7.0 with an apparent dimension of 35 arcmin x 35 arcmin. This was a difficult target to acquire since it's only above 30 degrees in altitude for about 3 hours per night.

QSI 683 CCD camera with Astrodon LRGB Ha OIII SII filters at -20C

Exposure and Processing:
This is a HOO (Hydrogen-OIII-OIII) composite with RGB data added for star colors. This composite is made from 27 hours of narrowband data and 9 hours of RGB data.
Ha: 70 x 10 min (unguided)
OIII: 90 x 10 min (unguided)
R: 90 x 2 min (unguided)

Ryan Haverson: LBN 576: Brain or Popped Balloon Nebula
I really enjoy doing these super dim targets that look like nothing in the individual subframes and only really pop once you get 10, or 20 hours on them. I could not find a lot of details about this target from the usual sources, but did find a source of info here:
http://www.arizonanightskies.com/lbn-576.html.
“LBN 576 (also known as Abell 85 and CTB 1) is a faint supernova remnant lying almost 10,000 light years away. Coincidentally, it is also around 10,000 years old. Until recently it was thought to be a planetary nebula
but recent studies confirm it to be a supernova remnant, the closest one known to Earth. Supernova remnants result from the explosion of a star in a supernova and are bounded by an expanding shock wave. They consist of ejected material expanding from that explosion. Also appeared on “Starship Asterisk,” the main discussion venue for the Astronomy Picture of the Day (APOD) October, 2014.”

Equipment:
