If money was not an object....
DAGE XLVM 640x480 Mono (Kodak 7.4 micron) or Grasshopper GRAS-14S5M-C
1384x1036 Mono (6.7 EXHAD).
The Grasshopper and DAGE support Region Of Interest, so you can reduce
the video size and image at 640x480 or even smaller.
However remember that the bigger the CCD pixel, the less detail your
getting per pixel. You can see the result of this in my comparison
image "FleaVersusDragonFly2.jpg" which is in the "Other" folder in the
"Files" section.
HTH..

I've been using the DMK21AF04 monochrome camera with my Celestron C11
and have been happy with the results using the LRGB technique with
Astronomik filters. (see http://gallery.mac.com/davidbleser#100065/Set-

It has become obvious that if I tried to increase the focal length any
longer than I get using the Televue 2.5X Barlow I would get a larger
image. But the desired enlarge Saturn image in taken through the blue
filter would be nearly invisible when taken at 7.5 FPS.
If I switched to a FLEA2 camera or some other camera (640 x 480)
supported by Astro IIDC would I be able to achieve more sensitivity,
hence a bigger or brighter blue channel movie?
Perhaps Milton will tell me what camera he would get if money was no
object for planetary imaging supported by his software.
