The Trifid Nebula (三列星雲) Messier 20
This may be the last shot from the backyard of this house. (If I say so, Clear Sky will continue, but...)
I wanted to take another picture as a souvenir, so I looked up at the sky every day, but there were only clouds and rain.
There was a little Clear Sky today for the first time in 15 days. When I pointed the telescope at it, I was able to photograph it for only 10 minutes.
Ironically, it's only 10 minutes long and seems like the best M20 I've ever shot.However, the coma aberration on the right side of this Reducer is hideous.
The rural observatory I am building with my friend is progressing well, the walls are complete and the Slide Roof is complete.
It looks like it will be ready for the new season.
この家のBackyardからの撮影はこれが最後かもしれない(そう言うと晴れが続いたりするが、、、)
記念にもう一枚撮りたくて連日空を見上げていたが雲か雨しかいない。
今日は、15日ぶりに少しだけ晴間があったのでそこへ望遠鏡を向けると10分だけ撮影できた。
皮肉な事にたった10分なのに今までで撮影した中で最高のM20に思える。しかし、このReducerの右側のコマ収差はひでーな。
友人と共同で建築中の田舎の観測所は順調に進んでいて、壁ができてSlide Roofも骨組みが完成した。
予定通り新シーズンには間に合いそうだ。
