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 -
