邊度有好天啊?

用數碼影相,影像是不是比普通的相機清晰的?

Dear Mr. Wah!,

Again a very good shot. But I'm wondering why don't you try the 3X barlow on Saturn, it should privide a better effect.

Best regards

只因為我無3x係手囉...

好靚呀今次~
最鐘意土星~

影像是否可以無限放大?
2x barlow 改為 5x powermate的結果可以比較看看.


(經neatimage處理才出得街)

如果用200倍可唔可見到咁大粒

睇同影爭好遠0架...
用 ToUcam 影, 經過電腦睇番會大好多.

你的螢幕幾大?用咩解像度?你離個螢幕幾遠來睇?

以上幾個問題都係想知道你睇到佢的視角有幾大.一般數碼相片可以用像素的數量來形容影像大小.
但是對於透過望遠鏡目視時,我們會用視角來形容物體的大小.

點解wah哥你咁鍾意影土星...

[Wah!]

因為:
佢夠光,較星雲容易影
佢靚
佢位置在天頂附近,seeing較低角度好

Surprisingly, last night at 11:00 p.m the sky was clean. I used my 15x70 binocular, and I saw so many stars in Mel.15, Mel.25, Cr 70, and M45. I counted that there were more than ten stars in the NGC 1981 cluster.

One of the best cloud-free nights I have even seen in this year.

明白，不過唔係個環?
