Cygnus Nebulae in Ha

Sky was pretty nice with good transparency, but some lonely clouds floated here and there making serious imaging session a waste of time. So, I tried something new. I mounted my H-alpha filter in front of Canon EF 50mm lens and pointed it towards Cygnus. It is really amazing how much nebulosity there is! North-America, Butterfly, Veil and even Crescent nebulae are nicely visible in this image and all this in very short exposure. I really need to focus on this for a while to get a real imaging going.
