Resolution from 10-few thousand. Good for extended bright objects, eg. The Lincoln Lab CCDs were not optimum, with a CT problem which can hopefully be addressed in software mode. This is being tested as a UW collaboration, with some supplemented DD time. FP imager would become available to community.
Remote operations is a concern.
Redesign of telescope top end part of this effort. Best test of equivalence principle of General Relativity. The aluminization facility would add another substantial increase. On the other hand, there may be a window given the needs in the SDSS project. Stubbs noted that if we take care of the mirror, realuminization may only be required once every 3 or 4 years, in which case the cost over the expected life time of the observatory is not so high.
