Thanks Stacy, Jim, Bob, Paul, and Jeff!

Sorry, I had lunch plans so I couldn't answer right away.

Ok... 120 minutes luminance unbinned (full resolution),
30 minutes Red and Green, binned 2x2 (half resolution)
60 minutes Blue, binned 2x2 (half resolution).

MaximDL was used to acquire and register the images. Mild
DDP was used on the luminance in Maxim. LRGB was composed
in Photoshop 5.5.

Seeing was excellent the night I took the luminance images
(Twelve 10-minute exposures) but transparency seemed 6 out of 10.
Tast night seeing wasn't quite as good but transparency
was up to 8 out of 10, IMHO.

Take care,

-Ray
