Hello Bill,

look at this page: http://www.sbig.com/sbwhtmls/ccdplacement.htm
Here you will find the new separations. It was announced in a mail in
the SBIG user group yesterday by Michael Barber.
Perhaps you can also add the two guiding chips of the MegaTEK from
OES. You will find the technical drawing at
http://www.stw.tu-ilmenau.de/~ff/beruf_cc/megatek/megatek.gif
(dimensions in mm). The guiding sensors are HP HDCS-1100
monochrome CMOS chips with 352 x 288 7.8 µm square pixels. The
specs you will find here:
