em10用32mm碳腳可以了我經常用來架heq5和80鏡
看來不錯,但有一些問題想請教:

32mm碳腳重量是多少?
是否必需是4節?感覺上第3,4節很幼
價錢是多少?

Check in 時同地勤講你有支望遠鏡要hand carry 上機

如無意外,佢會比個橙色嘅tag你叫你掛喺件行李上面

Tag上面寫住"BX T",係方便你過security check嗰陣證明件行李已經比airline approve咗

不過有呢個tag唔等如一定可以hand carry上機,因為最終決定權係喺flight crew手上,登機嗰陣如果佢地覺得唔安全,一樣係要寄艙

p.s.小弟上星期都坐國泰去咗轉台灣,成功hand carry epsilon 160上機

There is sophisticated mirror cell for large primary mirror.

However, is there any mirror cell that is designed for secondary? What kind of design will be used on your secondary which is as large as primary?

The dimension is roughly dia. 10mm x length 80mm. I found that there are a number of holes on the rocker and the mirror box. Th...

Hubble Optics UL16 F/5 @ PTC (27 Aug 2013)

Bought this telescope from Wongsir early this year. Although there were a number of problems with this telescope (e.g. balance), the optics of the mirror is really good. Using the laser collimator, the scope was finally correctly collimated last night. Under a starry night, the scope really exceeded...

How to get the driving permit? From my understanding, High Island Reservoir is 水塘禁區+郊野公園禁區. Ordinary permit could only drive to Hoi Ha/Wong Shek Pier.
