如今呢o的鏡似乎已經停產, 在國產鏡橫行的今天, 你地會有什麼心水推荐呢?
適合初學人士的平價望遠鏡 (Budget:港幣3000元)

記得早年有唔少初學人士買Celestron 80mm f/5, 114mm f/10 反射鏡......

Re: 適合初學人士的望遠鏡
Think no further than a Celestron C-8. Given its excellent optical quality, consistent QC, light weight, large aperture, good performance both in deep sky and planetary shooting, high portability and last but not least relatively cheap price one just cannot avoid the temptation of buying it as firstscope.sbod 寫:記得早年有唔少初學人士買Celestron 80mm f/5, 114mm f/10 反射鏡......

Except that you can grind your own mirror and provide it with excellent optical quality, purchasing any telescope other than C-8 is just a compromise.
C-8 is no doubt an excellent tool, with moderately large aperture, very good optical performance, much affordable price.
However, I don't think beginners, especially students, would spend more than 7K for his first telescope. It is massive, heavy, long focal length, and need a reliable mount and tripod.
當然, 如果佢有足夠的認識同指導, 我覺得C-8係無不可.

從你的經驗, C8的"optical performance"有何好呢?sbod 寫:C-8 is no doubt an excellent tool, with moderately large aperture, very good optical performance, much affordable price.

以我的角度來看, 如果著重重量輕, 體積小, 焦距長, 多於光學質素的話, C8無疑是一支非常出色的望遠.
但是C8對比於一支8吋反射鏡或5吋ED折射鏡的話, 無論在對比, 銳利和顏色上, 都比不上.
而價錢上, 現在反射及ED折射鏡的價格日漸下降, C8的售價反而不斷上升, 暫時看不到C8將來會有任何價錢上的優勢.
所以C8非常適合屋企地方較少, 而又離觀星地點遠的人.
至於你說它的壞處,
heavy - 如果C8都重的話, 我想你不適合觀星了. 我試過一手拎著C8, 載著三腳架踏單車二十分鍾去觀鳥, 十分輕便啊!
long focal length - 現在已有40mm目鏡, 配合C8, 只有50倍. 對於望遠鏡來說, 是很低倍呢!
need a reliable mount and tripod - 其實睇星可以不需要赤道儀的. 造一個你(dobs), 不就可以了嗎?

好像有點自相矛盾啊?sbod 寫:極度同意.ambcyli 寫:其實,應該係「看什麼」的問題
睇月球、睇深空天體、睇整個星座...應要用唔同望遠鏡
就算唔同目鏡都未必有好效果
以下都是很便宜望遠鏡啊? 都還未停產呢?
