Thanks to Jerry Foote who talked me through the process (Thanks again Jerry) I was able to shoot and assemble a couple of 9 panel mosaics of Comet Holmes tonight. Each panel measures 9' x 13'. With a 5% overlap I'm guessing that nets a field of about 25' X 35'. I tried to add them to the UA Gallery but somehow managed to delete my section... (And I'm supposed to be an administrator?) So I've planted them on my site until I can move them to U-A. Both were taken with a C-14 @ f/11, SBIG ST-10 binned 3x3 and chilled to -25°. Because the exposures were so short I did not need to guide. Each of the 9 raw images used in each mosaic were reduced with flats and darks before being woven into the final product.
