係度影星星
效果會點呢?

烏猶尼鹽灘(Salar de Uyuni)位處海拔3600米以上(大概和拉薩的高度相若), 是安地斯山脈的一部份。高山觀星當然有利, [高處不勝寒] 但要小心高山症

Dear Mr. Funooo, Tonight is not at all bad. Moon rise at about 7:00 p.m. but still quite far away from milky way. If we are early enough we could still catch some deep sky objetcs with the, of course, 16 inch PTC telescope. Aperture certainly helps in this situation. If you go, me go. If you don't ...

funoooo 寫:Do anyone come PTC tonight? I seem that is a nice day. I will be in PTC at 8:00. Are you come and join?

Are you sure, it is still nearly full moon [沒什麼嘛]

我之前二手購入了台Nexstar4(應該係舊款) 而家按制上下左右時經常唔識停，e.g.按一下左就左到唔識停 如果要拎去整，要拎去邊度整至得呢？ 如果想將枝鏡同nexstar鏡座分離 變做枝觀鳥鏡有無好提議點搞 thzz 多數是控制器壞了, 可拿出那個(除下電話插掣)去找BossKwan. 要不然, 如果有機會一起去PTC, 我有個相容的控制器可試試。 你的鏡是1300mm焦距, 用原裝25mm目鏡是52X, 那是無法手拿著來控制的 [頭暈目眩] 。即使不理要將鏡分離很難, 分離了的鏡沒有腳架接頭, 還是基本上沒法使用的。 BossKwan網頁有些Celestron馬卡式觀鳥鏡連小型腳架, ...

直到昨午，只食左兩個甜麵包，但係昨晚好好多了，差不多同平時一般。

慳咗咁多食飯錢, 又可以買新玩具啦

不過, 請小心身體, 還有好多東西等你教我 [跪拜禮]

其實 seeing 及 透明度 最大分别是什麼？ Seeing 是否大氣震動度，我有没有錯？ 如果根據天文台預報數據，怎樣去解讀當晚情况呢？ 簡單的可用維基 http://zh.wikipedia.org/wiki/%E8%A7%86%E5%AE%81%E5%BA%A6 "視寧度（英文seeing或astronomical seeing）,是用於描述天文觀測的目標受大氣湍流的影響而看起來變得模糊和閃爍程度的物理量。" 英文的 http://en.wikipedia.org/wiki/Astronomical_seeing "The most common seeing measurement...

今日去左海下, 本來諗住先去西貢市, 夜少少再返北潭涌, 但係見個天唔係幾得, 空氣好差....

途中仲見到西貢市好似有火足. 怕會塞車走唔到, 於是最終決定折返屋企.

得三輛車和兩個可觀察的天體（月球和木星）一算不算party [濕] [我不依] [遠目] [熱]

funoooo 寫:Excuse me. Can anyone tell me wha's the weather condition in Hong Kong now?

Dear Mr. Funooo,

The weather now is promising. I will go to PTC with the 16 inch telescope tonight.

Best regards
Chan Yuk Lun

I will probably go. See you.

At 3:55pm, the sun is shining again in central Kowloon, visibility is marginal (some haze but the Peak and Loin Rock are visible from central Kowloon).

I suggest to wait and see.

[讚美主] 十分厲害

白字的和金字的有何不同?

據聞在某些年份的七夕, 上弦月會約在牛郎星與織女星之間, 那就是鵲橋, 但昨晚月亮的位置差很多。
