Explanation: The beautiful Trifid Nebula (aka M20), a photogenic study in cosmic contrasts,
lies about 5,000 light-years away toward the nebula rich constellation Sagittarius. A star
forming region in the plane of our galaxy, the Trifid alone illustrates three basic types of
astronomical nebulae; red emission nebulae dominated by light from hydrogen atoms, blue
reflection nebulae produced by dust reflec |

East Veil Nebula，超新星遗迹的一部分
M8 (Lagoon nebula) and M20 (Trifid nebula)，把Ha当做Red的一部分合成的RGB
这张是把Ha当做L来合成的LRGB，Ha的星点比较小，画面更干净一些
M16，Eagle nebula |

milkyway的时候用rokinon 12mm f2。动物基本都是7d2+100-400 II。深空用a6000+100
-400 II。
3月在shenandoah照了lagoon nebula和trifid nebula:
更广一点的，大概150mm:
还有数据量严重不足的M101(Pinwheel galaxy)：
5月底去了rocky mountain NP:
还有great sand dune NP:
7月初去了美东dark site: cherry spring state park:
North America Nebula
仙女座M31
8月其实又去了一次，悲剧的辛苦两晚上sd卡丢了。。。从此没有再照星空了。
8月底游canadian rocky mountains，这里确实漂亮:
moraine lake
Two Jack
Lewis lake
9月底去了黄石，虽然已经算淡季了，人还是很多，不过还是看了不少野生动物的：
拍星空的时候看到了两个geyser一起喷发：
