The night of 2004 March 10/11 was exceptionally clear with good seeing, rated at 7 out of 10. I was able to see more detail on these planets than I have seen before. In the case of Jupiter, there were hints of considerable fine detail not shown in the drawings. I am not an artist: the disks were drawn free-hand. I have difficulty getting proportions right.
These observations were made from my back yard, using my 10" f5 Sky Mentor Dobsonian reflector. South is at the top.
