Ken, as you had the teleconverter on when you did the in-camera
metering (right ?) then you don't want to open up to compensate. (For
"allowing" I meant in comparison to not using it).
I did the brackets with the dslr as it responds to overexposure much
as a reversal film stock does.
Hotter = brighter (and risk of overexposing detail on the moon's
surface - pretty high-con object !) but one might want the moon to
It sounds like you're on the right track and may in fact have nailed it
