thanks for sharing.

對我這不是唸自然科學而是唸工程出身的，最讓我神往的物理學是牛頓力學，望遠鏡也以海爾望遠鏡止步，97年到美國時也獨自開車上柏洛瑪山，下午四時臨關門時衝進去，隔著玻璃幕牆看了這台雄霸世界數十年的望遠鏡數分鐘。我手上也有兩本"Perfect Machine"及"Palomar"，中間談及天文台選址的哲理、建台時遇到的挑戰及決擇，對我影響也很大。

所以我也很想訂這台鏡，奈何他們不寄往國外：

Murphy's Law of the Week:

"A highly complex system that works is invariably found to have evolved from a simple system that works."

今天的牛頓反射鏡，乃是近400年前牛頓的設計

Thanks for sharing! The scope uses CCD. I wonder what if it is viewed visually...

我用過最大而目視又成像優秀是40寸折射鏡，用500x看M5：
