======================================================================	

NB1: Detector (for OIII QE 95%, 2k x 4k, and for Halpha 2k x 2k) is 
ASSUMED to be available at the observatories.

NB2: This is based on the f/8 AAT implementation, with a field
of approximately 100mm linear size. WHT and/or VLT implementations
will be SIGNIFICANTLY more expensive.
