昨天聽收音機講西藏可能會下大雨, 希望社長的天文台可以安全渡過這個風險.
我沒有到過西藏, 其實社長的天文台的位置有沒有下過大雨的情況? 我相信一般是非常乾燥, 也有頗大温差.
社長 寫:現時訂購的終極西藏攝星鏡是意大利 Officina Stellare 500 f3.8 RiLA 攝星鏡,鏡身重80公斤,連同相機、另一台小攝星鏡,儀器總重會在90公斤水平。一般來說Paramount ME的標負68公斤是極度保守的,2008年到訪生產商Software Bisque時,老闆Steve大哥也說那只是一個偏低的數字,因為一直以來用家都是比較進階的愛好者甚至更多是專業天文研究員,他們對儀器都很懂,往往用Paramount ME來承載百多二百多公斤(例如NASA)的器材:

網上看到一段很重要的參考對話,原來那些頂級攝星人,標配都是50公分卡反配Paramount ME的![]()
Question :
20" RC Optical on a Paramount. Will it work with a reasonable amount of equipment? Basic CCD, etc.? Anything special I would have to do to make sure it will handle the weight?
Answer :
Yes, the Paramount ME will carry the 20-inch RCOS and associated equipment.
Since I've never personally mounted a RC 20-inch on a Paramount ME, I'm no an expert at what is required (other than lots of counterweights!).
Background:
The 20-inch RCOS with equipment exceeds the maximum capacity of the Paramount ME. Typically, the total payload is about 200 lbs.
Nonetheless, there are a number of (very prolific and well known) Paramount ME owners who use them. (And are quite happy with the performance, as I understand).
I'm not sure how many 20-inch RCOS/Paramount ME customers frequent this forum, so below are links to specific customers' web pages.
Bottom line: For the price, there is no better performing mount to carry the RCOS 20 inch telescope.

See July issue of Astronomy Magazine for a recent article (which, by the way, fails to mention the Paramount ME is the mount carrying the 20-inch RCOS).

Hope this helps.

上一張OS 500 f3.8 RiLA攝星鏡圖片,希望能趕及年底的大彗星投入拍攝。說實話,我個人不是什麼沉迷的深空攝影人,當這台鏡投入運作大既一兩年後,以該焦段拍上百多個天體,大既已圓了我這輩子的深空攝影夢,換作以前沒有西藏天文台時,打游擊方式可能用上10年也拍不完這麼多目標,又要離鄉背井餐風露宿在山上不知多少個晚上才能成事。當深空玩夠了,就像APO折射鏡玩到304APO雙筒後,便可以多放注意力在其他範疇上,例如製作天文望遠鏡、大口徑目視深空等。

这个网站上不去,被河蟹了。西藏900元人民币可以不饿死??才怪了,一碗牛肉面13块,只有两片肉,加起来还没一张口香糖的包装纸体积大。
