Norm,
Just snapped a Jupiter Venus distance with a 10MP DSLR 50mm fixed prime lens at f 5.6, ISO 800, 1/100 sec, infinite focus.
PDT 20:28:19 UT 03:28:19 6/4/15 Lat. 34° 10' N Lon. 119° 14' W
Total pixels center to center = 2973 correction = +14.5' multiplier = .37' (moa/px)
Total moa=1114.5' = 18° 34.5' camera distance
How did I do ?

Might be a nice exercise to photograph Venus, Jupiter over the next few weeks and see from photos if the separation is as Ephemerides predict. Combine this with Frank's exercise with Sextant and I can't think of anything more fun.
