20 inch telescope will proceed PTC tonite(19 May)

20吋鏡如期出動,今晚目標?當然是星系巢啦,不過不是室女座,而是大熊座的,廿吋鏡將於9時30分離場,原因? 因為要趕回家中覌察和拍攝木星,現在是木星衝期,唔好嘥。

Jupiter from window(18 May 2018)

Tonight the transparency is poor but stability is very good. I try hard to shoot Jupiter from my window, just in time to catch the great red spot at Jupiter's edge.

Telescope ;- celestron C11
Barlow : teleVue 2.5X Powermate
ASI174M + LRGB

Re: 雲南麗江双子莊園及高美古天文台考察及拍攝

有幾點好奇問題,希望參觀了的團友能回答。 双子莊園是否 "fully automatic remote control"? 1. 看圖莊園不是用dome裝置望遠鏡,似是用sliding roof 護蓋一群望遠鏡(但照片不見滑頂) 好天時,滑頂是否可 由遠端用家遙控打開 ? 2. 望遠鏡不用時應有鏡蓋防護,這個LensCap是否有電動裝置,也可由遠端用家遙控打開? Dear Boss Kwan, 1.|The sliding roof cannot be controlled by end user. It must be opened and closed by officials at s...

Re: Jupiter Tonite (13 May 2018)

Steady seeing prevail but the sky was very cloudy. Just caught the moment when Jupiter appeared at cleavage of clouds. The moment was very brief, just enough time for me to take the L,R,B and G captures. The seeing was very steady, however. Telescope : C11 + TeleVue 2.5X Powermate. Camera : ASI174M...

It could hardly believable that a 76900 Newtonian is able to perform in such level of performance.

Re: 鏡仔影木星

Incredible!!!

3 inch f/12 Newtonian is using spherical mirror. It is one of the cheapest astronomical telescope ever made. But the result is stunning.

Re: 自制150 牛頓折射鏡(折射反射兩用,消色差APO或普消

這設計一點也不實際,6吋 f/5 的APO 物鏡就算有錢也買不到,就算天價買到也不會比的6吋牛反有超大幅度的質量提升,若果用6吋 f/5普消透鏡,二次光譜將大得無法接受。

想來想去,想不通這設計有何實際之處。
