Well actually, even though the Hyperstar is designed for a 27mm chip diagonal, Andreas has proved here http://astrob.in/78743/B/ with the correct flats it will work with 45mm chip. He's using the Atik 11000. Granted its not the 16803 but its pushing the boundaries.

Narrowband imaging is also possible at F2 where bandwith shift is present. Andreas is also testing new "High speed " 10nm Baader filters with his Hyperstar set up. See here http://astrob.in/99398/0/

But a 10 position filter wheel Might have to remove the secondary off Greg's 17''
