Single Exposure Project #1 3 minutes Rosette Nebula

First shot is 3 minutes single exposure Rosette Nebula
I've been trying to see what I can see with OSC's single shots from time to time, but I thought I'd push it a little further.
However, the sky here has a limited exposure time, so the condition is 1-3 minutes. And the target also needs to be reasonably bright, so there aren't many celestial bodies to target.
2nd picture is just unlinked stretch photo

以前からたまーにOSCの1枚撮りで何が見えるか試していたが、ちょっとそれを進めていこうと思った。
ただ、ここの空は露出時間に限界があるので1−3分で何が見えるかという条件が付く。そしてTargetもそこそこ明るくないと無理なので対象の天体はさほど多くない。
2枚目は撮って出しのUnlinked Stretchだけのオリジナル。
