It might just be me, but I didn't find too much of a difference between the white charcoal and the Conte' pencil. The Conte' seemed to write a *little* easier but I was hard pressed to find it a whole lot different than the charcoal (other than the price). Maybe I just don't have a keen sense of media yet.
I also did a sketch of Jupiter but it was laughable at best. I think it would probably be done better with graphite pencils on white paper. I was overjoyed to see the great red spot and a transit of a moons shadow (on the same day no less). I had never seen either of those before in my 8" coulter (piece of junk) dobsonian. I am really liking my small refractor. Aperture doesn't always rule in my book.
Please forgive this image and probably many to come as I had to take a picture of it with my cell phone and save it to my computer as I don't have a scanner out on the road with me (truck driver). I also had to use The Gimp to enhance the contrast a little as my camera on my phone leaves pictures a little washed out looking.
