香港天文論壇

其實中國大陸以前都有這些食品安全, 公共衛生和假貨等等的問題. 以前是知道, 到現在才知道, 都算是社會上的進步了. 至于現在大陸生產的東西好不好, 這就要看你過人的要求了. 在大陸, 要求高當次的都願意在本地購買. 一則是怕買到假的進口貨. 二則是比較相信外國的品牌 (有些貨或有些部份也在大陸加工, 相信他們的QC做得好嚴謹). 要求高的要買日本生產的 (個人意見), 因日本人做事講求精細和精密, 絲毫不差等的優點. 缺點是好貴. 國產的都是量產中低當次的貨為主, 優點是相對的較平. 這都是一分錢就是一份貨的定律. 要求又要平 (大陸的價錢) 又要好 (日本的質量) 的, 都是不設實制....

If you read the data from Hong kong observatory every day. it tells you the exact time the moon riases and sets as well. For today, the moon rainses at ten pm and sets at about seven in the morning. So, tonight is a good time for the first half night for star obersvation.

是昨晚在坪州拍的!! 不錯!

到時請通知聲. 我都想去睇.

是不是八月中旬有一個英仙座的流星雨看?? 在那天能看到?? 用甚麼望遠鏡才能睇到??

其实不是香港人难相处, 只是大家成长在不同环境下, 同意TONGKW的说法, 只有给点耐性和时间去沟通就可以. 我也经常在大陆做事, 也不觉得国内的人难相处.

Mr. Chung, Working late tonight unitl 6 : 30 pm. Maybe next time. Got your contact number.

睇星, 叫埋我, 我都想去.

到目前為止, 覺得今年夏天的天藍了, 視野及能見度都很好. 空氣質數大有改善. 印象中比起前幾年好得多, 大大有利于觀星等活動. 應該是人們注重環保有關.

Very detail and experience pcs of work.

Mr. Chung,

Have no hear from you for a while. I must thank you again last time to teach me the way to use my telescope. 上星期比較忙, 所以沒有去睇星.

你什麽時間再去睇星?? Please also let me know. I would very much to go as well.

I am new to this but correct me if I am wrong. I think the quality of the photo depends on the following factors:-

Your location and the time to take the shoots.

Your konwledge of the enviornment and the target.

Your equipments as well as your personal exereince of using it.

是是Shhinx mount 比 CG 5輕好多, 以至方便帶上?? 在 cloudy nights 內, CG 5 mount 的評倫都不大好用??

Your photo is under exposure by 3EV or so. Should be better to set at higher ISO couple with larger apeature.

I AM NEW TO THIS. CAN I JOIN YOUR GROUP?? I DO NOT HAVE ANY TELESCOPE BUT VERY INTERESTED, HO DO I GO AND WHAT IS THE BEST TIME??
