      Description

      This is 4 panels, each with 18 H-alpha subs of 1200 seconds each.

      Shot whenever the sky allowed on nights of June 18th, 19th, 22nd, 23rd, 26th, 28th, 29th, and July 2nd and 6th. I only had a couple nights to knock out a bunch of it, the rest was shot here and there between clouds and before getting shut down by fog. Almost all was shot in 100% humidity. Panel 3, which is at top left now after rotating the image, was all shot the night of full moon. I was surprised how well things blended together considering the wide variety of conditions and darkness.

      Revision B is a starless version. I may come back to this later and try to get some color if I can get my camera oriented correctly. I pulled the camera today because I'm getting a new scope tomorrow. If things go well maybe I can get it lined out and ready to use in a few days. :-)
