focuser 中文意思是什麼
focuser
解釋
焦距放大鏡聚焦裝置-
The focuser has large anodized focuser knobs with rubber o - ring gripping surfaces for a firm grip and frostbite - free handling in cold weather
那轉接端已經用強氧化處理的表面鍍膜為寒冷的天氣堅定的緊握和級低溫的穩定使用。 -
Perhaps for such reasons, the term " prime focus " is increasingly being used in a more general manner : in systems in which there is only one place where there is a focuser - - where an image is formed and you can get at it with an eyepiece or some other equipment - - that location is called the " prime focus "
可能出於這些原因， 「主焦點」一詞正逐漸被人們以一種更寬泛的方式使用：在只有一個聚焦裝置的光學系統中，那個成像的、可以用目鏡或其他裝置攝取像的位置，就叫做「主焦點」 。 -
With your eye close to the focuser, you can see the primary mirror reflected in the secondary, and the secondary and its spider in turn reflected in the primary
把眼睛靠近調焦座，你會看見副鏡中有主鏡的反射像，而副鏡和它的支架也在主鏡中有反射像。 -
Like the primary mirror, the eyepiece has an optical axis, and this axis should be aimed at the center of the main mirror for best performance ? though in practice it is the center axis of the focuser drawtube that you aim at the primary mirror
目鏡和主鏡一樣也有光軸，光軸應該對準主鏡的中心? ?盡管實際上，目鏡的光軸對準的是調焦筒（相當于調焦座）的中心。 -
Finally, inside this reflection of the secondary, you can see the focuser drawtube and your eye
最後，在副鏡的反射像中，你能看到調焦座的伸縮管和你的眼睛的像。 -
Step 2 : here you adjust the tilt of the secondary mirror to aim the focuser ' s axis at the center of the primary
現在你已經調整了副鏡的傾斜程度，把調焦座的中軸已經對準了主鏡。 -
If not, either the secondary holder or the focuser ( or both ) needs attention
如果不是這樣，要麼副鏡支架或調焦座（或兩者）需要注意了。 -
Put it in the focuser and observe the reflection of its shiny 45 - angle face in the primary
把它放到調焦座上，觀察它的45度角的反射面。 -
This rotator device is still used today for all takahashi focuser from the 2 ” to 4 ” focusers and all astrographs
該旋轉介面至今仍應用於高橋的2 」到4 」的調焦座以及天文攝影中。
