Object Name: Pythagoras
Object Type: Lunar Crater
Location: Bristol, UK
Date: 16th April 2011
Media (graphite pencil sketch at the scope and then digitized using graphics tablet and Photoshop)
I usually sketch in some detail at the scope (mainly HB and 2B). I then scanned the result into Photoshop and used a Bamboo Pen graphics tablet to remaster the sketch. The final sketch was then “blurred” a touch to simulate the actual view which is never as sharp as I would like to see!)
Observational date: I use a Nexstar 8SE teamed with a Hyperion 8-24 mm zoom. Most of the sketch was at the 8 mm stop and was drawn in good seeing conditions. The moon was 13 days old.
I could see the two central peaks but not sharply. However the terracing along the rim walls was obvious as was Babbage to the south. Because of the foreshortening I could see shadowed craters to the north.
