1st North American Nebula (Hydrogen Alpha) - 2nd light in SBIG

I had intended to setup for my 1st +Virtual Star Party in over a month or two, but the weather had other designs.  I did manage to solve 2 big hurdles this night.  First, I got the SBIG CCD closer to the Coma Corrector with some shorter spacers which got rid of the comet shaped stars from the 1st light of the camera.  Second I got the OAG and guide cam focused and found some guide stars in the hazy clouds that kept all but magnitude 2 stars visible by eye.  I setup and took images not expecting much, but after 6x300s of Ha I found something I've never seen before in all my attempts with various scopes and cameras!!!

Yay!  Not too shabby for no darks, flats or any other calibs.  Merely 30min on a rather large nebula that has always eluded me!
