I can only get pieces of it at a time. This is one a mono camera with halpha filter would be a great help with. Then use this one for the color data.

Beautiful picture John. You should really get a 2" UHC filter that lets both
Halpha and OIII pass (e.g. Astronomik UHC, which probably will have to be used in addition to an IR blocking filter), this would be ideal for objects like this... Stefan "John N.
