Thanks very much Richard - yes, I followed that up and their paper is my reference in post 4 - Eden's thread was nice happenstance, since I hadn't been able to find anything else that confirmed the simplified relationship. The video implied that this type of relationship is commonly known ("astronomy 101" from memory), which is what I expected, but couldn't confirm. In any event, hopefully it is useful to bring it to the forum's attention, since it is dead easy to use in this form and clears up all those "what difference does Fnumber make" type issues.

you have just moved from OSC to mono - do you have any feel for the relative sensitivities of OSC and mono? - ie do you think that it is reasonable to assume that the QE of an OSC is about 1/3 that of an equivalent mono chip?
