Some of my favorite views are:
7x50 in bright daylight, when my pupils are 2 or 3mm
16x70 stopped down to 46mm for double stars
(Hooray for wasted glass around the edge of the objective! I positively do boast about it!)
16x70 at full aperture for faint fuzzies
(Hooray for compact, lightweight, large and overly fast optics! Stopping down easier than stretching out.)
By the way, Glenn, do you think BK7 is significantly more transparent and homogeneous than Bak4? And, is it really much cheaper?
