Thanks. Only by luck I got steady seeing at home.

Tonight excellent seeing again appears, it is a good chance to capture Jupiter together with its nearly turn away great red spot. Looking at the picture you will see the great red spot lying just at the left edge of Jupiter, nearly disappearing into the giant planet's back. Telescope : Celestron C11...

We are stilling having continuous fine weather and Jupiter is shining on the sky every night. It is a pity that we don't nail it down and so I did it. This shot is from the night of 21 of May, when the sky was still having very good stability and good transparency. Telescope : Celestron C11 Camera :...

昨天晚上除了沒有云外 , 穩定度世很好 , 咁梗係映木星喇 , E+係木星大衝期 , 真係唔好浪費上天所賜良機 , 木星猶如一個獨眼巨人咁望住你。

Good weather prevails and chances of shooting Jupiter are not to be missed. The stability was very good though clouds were coming in and out.

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。

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.

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...

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...

As title.

I really want to see this movie but cannot find it. Does anyone know the source of buying the bluray or DVD ?

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