月掩金星活動後記

昨晚到屯門黃金海岸,用前天才收到貨的伽利略望遠鏡(想不到第一任的梅夫人是來自美國)觀察。準備期間遇上了Bingsze和鏡神,並與Alan談了一陣往事。約7時半左右,我好不容易才把望遠鏡對準了月亮──這夫人可能第一次出動,難以控制,可惜月剛掩金星時正好給雲掩金星。稍事休息期間,與上了WFC-3,談了會,又準備觀看生光現象,兩人費了九牛二虎之力,才對準了月亮,兩人輪流欣賞:金星慢慢從月亮背後走了出來......

P.S. 這鏡子觀月真好,不會有色差,輪廓清晰

梅西爾,

「第一任梅夫人」已是名花有主,這稱呼吾係你叫呀 !

一則八掛資訊: Charles Miessier 掛住揾彗星多過關心老婆死左,見
http://www.universetoday.com/2009/06/26/happy-birthday-charles-messier/

“..... If you think today's scandal sheets at the grocery store checkout are bad, then know they couldn't hold a candle to what aristocracy could do back then. According to research, a malicious legend is reported by Jean-Francois de Laharpe, written in 1801, that the death of Messier's wife had prevented the discovery of another comet which would have been his thirteenth, and Messier was more desperate because of the lost discovery than of the death of his wife (especially as this comet was discovered by Montaigne, whom he didn't like).”

那支伽利略式望遠鏡的視場很窄,既然它有目鏡附件可以改為開普勒式望遠鏡,就多 D 用這目鏡吧,它的視場較寬,用來觀天更好,個晚我要觀測月掩金星不能分身,否則會介紹那晚的新月有那些地方可看。宜家補番數,不知你有無見到在下圖 No. 1 至 No. 8 的月面特徵,它們都有一段歷史故事哩。
