[漢羅] 直接投影：提 tī 手--lih ê 月娘

你毋免用望遠鏡 to̍h 知影伊這馬咧看啥物。 咱若是 kā 望遠鏡 看著 ê 景色投影到一个較大 ê 所在，應該是真利便。 因為會當 kā 一粒 足光 ê 天體 傷強 ê 輝度 沖較薄咧。 這款 沖較薄咧 ê 投影技術實在是真利便，咱會當 kā 用 tī 像 太陽 這款足光 ê 天體，尤其是拄著 日食 ê 時陣。 這張孤張感光 ê 相片，to̍h 是 kā 這个投影技術用 tī 月圓 時 傷光 ê 月球。 二月 ê 月圓出現 tī 兩禮拜前。 Tī 一寡北爿國家 ê 文化內底，這款月娘 to̍h 叫做 雪月。 投影 ê 儀器是 直徑 62 公分闊 ê 望遠鏡，to̍h tī 法國 Alps 山頭 ê Saint-Véran 天文台 內底。 直接看月圓時 ê 月球是有較簡單，因為伊無 遐爾光。 毋閣你 to̍h 無法度看著遮爾濟細節矣！ 後一擺 閣拄著月圓，會 tī 3 月 17。

[English] Direct Projection: The Moon in My Hands

You don't have to look through a telescope to know where its pointing. Allowing the telescope to project its image onto a large surface can be useful because it dilutes the intense brightness of very bright sources. Such dilution is useful for looking at the Sun, for example during a solar eclipse. In the featured single-exposure image, though, it is a too-bright full moon that is projected. This February full moon occurred two weeks ago and is called the Snow Moon by some northern cultures. The projecting instrument is the main 62-centimeter telescope at the Saint-Véran Observatory high in the French Alps. Seeing a full moon directly is easier because it is not too bright, although you won't see this level of detail. Your next chance will occur on March 17.
