Jupiter, Io and Europa
Sketch and Details by Carlos Hernandez
I made an observation of Jupiter on August 3, 2008 using my 9-inch F/13.5 Maksutov-Cassegrain. Much detail was noted over the planet, especially the South Equatorial Belt (SEB) and Great Red Spot (GRS). The seeing conditions were above average (6/10) for a short time before the clouds came in and ended my observing session. I welcome any comments that you may have on my observation.

Carlos,
A superb drawing of Jupiter, Io and Europa. Fantastic capture of detail in Jupiter’s atmosphere. Impressive notes describing what you have sketched. It is always a pleasure to see the beautiful drawings you post here.
