This nebula is affectionately referred to (or is that "humbly" referred to) as Thor's Helmet. It is a "bubble" nebula (the helmet part) that is generated by the intense radiation of the center Wolf-Rayet star carving this bubble out of the local gas and dust. The "wings" on either side of the helmet complete Thor's iconic head piece.The nebula is about 30 light years across and resides in the Canis Major constellation -- be sure to visit when you are in the area : )
This image is the "first light" of my new TEC 140 scope. Though I got the scope back in November, my imaging attempts were thwarted by weather until last week -- but it was worth the wait! I am very impressed with this scope.
For all you "tech heads", here are my imaging specs...
TEC 140 w/ field flattener
STL-11000M -20C
LRGB (210,30,45,60) RGB binned 2x2
CCD Stack, CS4

Great target for your TEC140 first light!
Thanks, John. I've always loved the colors in this object -- you do not see too much "teal" in space : )
