David's Earthshine shot reminded me to post this test shot from a few days back. This was taken with the 145M camera at prime on the 127 ED with an exposure time of .01s! A stack of 20 shots (none rejected) with AA4.
No cropping David, the chip in the 145M is 1/3" and is 1360*1024 pixels as opposed to the APC sensor in the Canons. I actaully have a 0.8x FR in line as well to compensate for the small sensor. If I don't do that I would image at about 1.3" per pixel. Not much point in that with seeing at 2.5 to 3" on a good day. The 145 is a cooled mono CCD camera, this one:
