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.
