香港天文論壇

hello 各位. 講起輕巧既裝備, 我有感而發... 起得在6年前初始接觸天文, 見同好 d 鏡大支, 好看, 就覺得最緊要大... 於是不段去轉鏡, 由 3" 反-> 4" 折 -> 5" 折 -> Meade SN 8" , 但最後都不及一支 90mm 折反 + K mount 好, 因為香港的環境真係不適合帶這麼大支鏡出街, 我試過在東涌去水口因為支鏡大, 個個巴士司機都話不能上, 等的士一架都冇, 結果果晚要回家...... 支鏡都係冇用過....... 現在 SN 8 封了好多塵. Why don't you share it out at Water Mouth. They a...

不行了，聽日去工幹，希望大家今晚玩得開心！！！

你遲去了點。我在石壁，星匯點都看了個多小時

昨晚(21/6)個天真係正，我同壹班(星匯點)嘅朋友去咗大嶼山石璧紅十字會營，到深夜用6”馬卡高倍睇咗好耐月亮。下星期六同壹地方會有25吋口徑反射鏡出現（香港天文學會觀星營）。 我也成功使用 ETX-70 看到土星、木星和木衛、Alberio 雙星、月球，靠TONGKW 的貼士，成功將 ETX-70 align 到。 使用 MacBook + WebCam, 效果不理想，主要 ETX-70 追蹤星體的震動太大，WebCam stack 的都是震動的影像。 此外，本來想接駁其他有更加穩定的 mount 的望遠鏡，例如 TONGKW的馬卡，但原來對焦上，馬卡需要接駁，而其他人的望遠鏡也要收 （月...

何事如此感觸？

XR250 寫:影木星，就更加唔怕月光光。

最怕無熱誠。

If I am not too tired, I will try my Macintosh + WebCam + ETX-70.....
By the time I get home I can check with my Macintosh astro software Equinox (this software is really feature rich, I have to explore it !!)

我今日過關去深圳﹐路上見個天空好清。我星期日入星匯點那個 camp﹐希望天氣一樣咁好。
可能大家今晚已經急不及待出北潭涌﹑水口啦

Dear telescope enthusiasts, The iOptron lacks the tracking ability of equatorial mount but still needs a counterweight. ( attention :- the so called second telescope is actually a counterweight ) . I see no reason why this commodity can survive in long amateur astronomy market. With the unexpected ...

WongSir,

Any stock ?

Please PM me.

Yes. I have made a small bracket to mount the red-dot finder and a 9x50 finderscope onto the dovetail of the C6 for using with the Z2. My C6 is part of the Celestron NexStar 6SE package. The red-dot finder is from Ap Liu Street last year. The finderscope is an very old one, Orion 9x50 from USA. I r...

我常用 Mizar K Mount裝上 C5 作壹般目視觀測算是可以及幾啱用，但同樣裝上C6就發覺有些不夠力，尤其在用高倍時有頗大震動。 Maxvision K2 經緯儀是仿日本 Mizar K Mount，我相信裝上C6這樣使用的效果與我說的會是差不多。 Thanks. For your C6 + Z2 + Finderscope and "red-dot" pointer configuration I guess you have mounted the findscope / red-dot pointer onto the dovetail of the C6, isn't it ...

I am still using Alt-Azmuth mount, but this tutorial on equatorial mount looks complicated. Can someone explain it in plain Chinese ?
