I
asked someone off-list about the difficulties of photographing planets with
short focal lengths. I saw a table in Covington's book (p. 75) that described
the size of Jupiter on 35mm film with various focal lengths. At 1000mm FL,
Jupiter is only 0.2mm in size. At 800 FL and below, Covington says "--"... or
too small to measure.
I'm
guessing from this it's hard to even see the rings of Saturn at 800mm and below?
Thanks,
Rex
