Got the final bit of data on this one last night. This is a 2-framer using the Canon 200mm prime lenses and Trius M26C OSC CCDs on top of the Paramount ME.
Main North America frame is 9 hours and 40-minutes total using 20-minute subs. The right hand frame (with Deneb) is 10 hours and 20-minutes total data time using 20-minute subs.
The ONLY negative thing with the 200mm lenses is the bad ghost flaring from any bright stars in the image. This makes it an ideal imager for regions like IC2087 where there are hardly any stars (let alone bright ones) to be seen.
