Hi Alan,

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? I've got a TEC 

250/f12 Mak that I'm going round and round over camera choices, and 

wanted to get some baseline data for a similar scope and known camera 

combination.

Thanks,

Kurt Mihalco

Had a brief (and unusual) midnight window of good seeing saturday 

night to capture 

saturn. Hopefully the second half of this apparition will have more 

opportunities than the 

first!

750 frames from 4500 were used for luminance at f45. RGB filtered 

images were captured 

at f32 and resized. DMK21BF04 webcam and A-P 10" mak/cass.
