Thanks Alan,

This info will help me figure out what pixel size I want to go with 

in the camera I select.

Regards,

Kurt

In this image, what exposures were you using for 

Luminance (F45) and R, G, and B (f32)?  What FPS were 

you acquiring at, and was it the same for all, or slower for 

Luminance and Blue? 

The unfiltered luminance was capture at f45 with 33ms 

exposure at 30fps. Gain was set between 850 and 900 for 

the DMK (there were passing thin clouds). The RGB 

streams were captured at f32 at 66ms exposure and 15fps. 

Gain was adjusted from about 850 (green) to maximum 

(blue) with the red somewhere in between. The color 

streams could have used more exposure. The luminance 

could have a longer pocket of good seeing - 750 frames 

was not quite enough, but of course better than none!

Hope that helps -

Alan
