Subject: First Jupiter of '07

Finally a break in the morning sky with Jupiter due South but very low in the sky, just clearing 

my garage roof.  Imaging through RGB filters actually helped to cut through turbulence and 

provided much more contrasty details than unfiltered mono image.

Alan:  how do you combine R+G for luminance?  I actually thought my B + G were the better 

images, R was much dimmer and less contrast.
