Orion on Film
Credit & Copyright: Matthew Spinelli
Explanation: Orion, the Hunter, is one of the most easily recognizable constellations in planet Earth's night sky. But Orion's stars and nebulae don't look quite as colorful to the eye as they do in this lovely photograph, taken last month from Vekol Ranch south of Phoenix, Arizona, USA. The celestial scene was recorded in a five minute time exposure using high-speed color print film and a 35mm camera mounted on a small telescope. In the picture, cool red giant Betelgeuse takes on a yellowish tint as the brightest star at the upper left. Otherwise Orion's hot blue stars are numerous, with supergiant Rigel balancing Betelgeuse at the lower right, Bellatrix at the upper right, and Saiph at the lower left. Lined up in Orion's belt (left to right) are Alnitak, Alnilam, and Mintaka all about 1,500 light-years away, born of the constellation's well studied interstellar clouds. And if the middle "star" of Orion's sword looks reddish and fuzzy to you, it should. It's the stellar nursery known as the Great Nebula of Orion.

有没有暴光参数？

哎
看的我心里酸酸的。

猎户座是我现在晚上唯一能认出来的星座，可怜我那800多度的近视啊……

好象这镜子的像差也不小哟
边缘的星有些变形了，成小段弧了

不过猎户座可是真漂亮啊！

不错，很清楚的，我喜欢：）

非常漂亮。
这照片基本上是用标头，光圈缩小成2.8左右，加上柔焦镜，跟踪曝光15分钟左右。
当然，拍摄地点的光害比较小。

嗯不错，还可以分出来，，，
