Conditions: Average, Mag 3-4 Skies

Camera: SBIG ST-8E/CFW-8, -20°C, CS 3nm Ha filter
Comments: Shot over two nights. This is my first attempt at creating a mosaic so I thought I would try with just two images. The Ha simplified it even more since I didn't need to worry about color. There is more to this nebula than I have here so I am going back for the rest !!
