Learning to draw involves learning to see, so liberally sprinkling
your astronomical notes with drawings of "how it was" is doubly
rewarding.
This is "how it was" one night in the summer of 1994 when fragments
of Comet Shoemaker-Levy-9 center-punched Jupiter time and time again.
I started drawing Jupiter several months before the main event, and
the difference in detail apparent at first and fiftieth glance
was at least the difference between using a small, 3-inch refractor and
using a sharp, 12-inch reflector. I mean to say that at the beginning
of my planetary observing career, I could see no more through a 12-inch
reflector than I later learned to see in a 3-inch refractor. Practice
means as much as a lot of high-dollar glass does. Of course, what one
can see in big glass during steady moments after all that practice can
be literally overwhelming. It's hard to know where to begin to study
and what to draw first when all that detail leaps forth. Are you new to
planets and find that hard to believe? So did I.
The field notes on the left were made at the eyepiece of a 5-inch
refractor and a 16-inch Dobsonian. The finished drawing on the right
is a leisurely effort using Adobe PhotoShop and a graphics tablet.
The comet scars got most of my attention: lots of fine detail begged to
be recorded elsewhere on the planet and had to be ignored.
Back, back, back!
