This shot was taken with the iPhone aimed afocally into the eyepiece of a 20mm Erfle on the 120mm f/8.3 achromat with 1000mm focal length,
which yielded 50x.  I must have been holding the phone far enough away from the eyepiece that I captured a lot of extraneous ghost images
and glare, but that has been edited out to just leave the Sun image.
