Saturday evening a group of us were setting up for observing near New Ringgold, PA when we were surprised by the sudden appearance of a bright "cloud" in the southeast.
It turned out, of course, to be a test cloud. Since I was not yet set up, I yanked out my pencils and made a sketch as fast as I could. Conte pencil on black Artagain paper, which I was testing and found very difficult to work with.
Those of you who have used this paper, do you "prep" it somehow to make it easier to work with in the field?
