That's a beauty Jase. I take it this is a Northern Hemisphere object?
Where was the scope located?
Did John take the data and you process it?
Very nicely done and those fast Newts when they work are an impressive machine.
There has been an interesting thread by Massimo Ricardi on the Astrophysics website and there appears to be a number of very fast (F3.6 or less) large aperture astrographs being designed.
Imagine a 600mm F2.8 astrograph?
In the meantime the ASA16 if it works would be a nice substitute.
For narrowband the U09000 might even be better with that bit extra QE
or better still a Proline 9000 as then you get the RBI control you need with that chip. Come to think of it Apogee brought out an RBI fix as well.
