|It took an hour and a half to do the sketch for this drawing. Poor old Bizibilder was tired at the end of it – far too much concentration!! |
Anyway he is quite pleased with the result!
Evostar 120mm x 200
|These two show a bit of the moon on two different nights. The long straight shadow is caused by a fault (or split) in the surface of the Moon where one side has dropped relative to the other. The top picture is only a quick sketch done on April 22, the second is a proper drawing done last night – May 21st. |
Both 120mm refractor x200.
|The difference in the shadow cast by the fault is very different in the two pictures, although the difference in the Moon’s age (ie the time from the last New Moon) is 8.2 days and 7.8 days respectively. The fault is around 67 miles long and between 300 and 900 feet high. It is not a vertical drop! and has a shallow slope – you could probably walk up it!|
|A very thin crescent Moon tonight – only 3.8 days after New Moon – Quite a “wide Field” drawing of the area around the Mare Fecunditatis showing the craters Colombo, Cook and Gutenberg along with the surrounding landscape and smaller craters. |
