I made an observation of Venus on February 10, 2009 (00:30 U.T.) using my 9-inch (23-cm) F/13.5 Maksutov-Cassegrain (248x) under average to good seeing conditions (5-7/10). The central meridian was 271.7 degrees West, phase 35% (p 0.350), and apparent magnitude of -4.6. I was using a magenta (Wratten 30) filter, enhances both red and blue features and darkens green ones, to bring out the subtle albedo features over the Venusian cloud tops. I was able to make out delicate albedo features over the visible globe and especially along the terminator. Obviously they became more apparent when the seeing steadied for brief moments.

Carlos,

An amazingly detailed observation!

Bravo!


I'm a little confused about time zones. Was this a daytime or evening observation, Carlos? I ask because of the possible glare of the bright planet.
