Jupiter with Canon 60Da Movie Crop Mode

This full size, cropped image was taken this evening with the Canon 60Da in "Movie Crop" mode.  This mode gives a 1:1 pixel ratio and a 640x480 frame with 4.3um pixels. This gives a corresponding image scale of 4.3/4550 * 206.27 = 0.195 arcsec/px using the TMB-130SS refractor and a 5x Powermate.

At ISO800 and the slowest shutter speed of 1/60sec, the histogram peaked at the 1/3 level. I wish this were a bit higher but I hesitate to bump up the ISO gain.

The seeing this evening was terrible, so I expect to get much better detail when the conditions are better.
