豆貓的鏡子--Gregorian 格高裡望遠鏡

[Subaru]

Dear BeanCat,

I saw the result from your new telescope.

Are you consider the poor contast from installation of Baffle (中間個枝黑管) system

Baffle is important for a compound telescope for improvement the overall contrast, especially for viewing daytime objects.

However, the figure and alignment is also required to be checked for getting a higher micro-contrast of the lunar and planetary details.

oh. 我唔記得答 august 添.
我係有一個暫時性0既 baffle 的. 用黑色畫紙 sip 住先. 不過畫紙0既反光都幾勁. 睇月亮就好覺.
所以...... 你可能諗唔到, 夜晚睇野, 唔加呢個暫時0既 baffle contrast 竟然仲高!!!
我會試下用絨紙代替, 睇下效果會唔會好0的.

Dear Miss BeanKitty and ATMs,

Judging from th emoon shot, unfortunately, the low contrast comes from spherical aberration rather than light leakage. Hence baffling the telescope cannot help, I'm afraid.

Anyway the making a Gregorian is a good ( and brave ) try. I have to make my personal applause to Miss BeanKitty.

Best regards

wa...

其實呢支鏡我主要都係試驗性質. 冇諗過會好好質素.

不過我覺得整呢支鏡最好玩0既係, 佢既每一部份都係自製.
包括主鏡, 副鏡, 主鏡座, 副鏡座, 目鏡座, 鏡箍......

雖然有好幾個部份都係由磨鏡班0既剩餘物資改裝出來, 不過諗下點設計, 點改裝, 個過程真係幾好玩. ^^

豆貓你好,我想要中文的設計和製作格雷果裡望遠鏡的資料,簡體或是繁體都行,我不懂英文,苦啊.你如果有,就請告訴我,再聯繫,先謝了.

豆貓, jinbin1963想問你要設計資料, 不知他是否看完你的鏡後也想自製一個呢?

[豆豸苗]

其實我也沒有很多有關的資料. 我只有這個 excel. 我嘗試將其中的英文譯做中文吧.

只要輸入頭五個數值, 它就可以幫我計算出主鏡和副鏡的焦距和有關的數字.

對啊,怎麼打不開啊?
