The Great Barred Spiral Galaxy L-RGB Ver (大バード・スパイラル・銀河) NGC1365
I photographed the galaxy once a few years ago, but that time I was unable to take an exposure for even an hour because the roof of my neighbor's house obstructed it.
Still, the characteristic Z-shaped arms were visible, so I decided it was OK at that time.This time I wanted to see the pale arms that wrap around themselves like the circle of wisdom, so I planned to take a lot of time to take pictures, but clouds and rain got in the way, and it took me 4 days to take pictures for just over 5 hours, but I could clearly see the circle of wisdom, so this season Is this OK?
数年前に一度撮影したことがある銀河だが、その時は隣家の屋根に邪魔され1時間も露出ができなかった。
それでも特徴的なZ型の腕が出ていたので、その時はそれでOKとした。
今回は知恵の輪のようにまとわりつく淡い腕を見たかったので、じっくり撮る予定だったが、雲と雨に邪魔され4日かかってやっと5時間ちょっと位しか撮れなかったが知恵の輪がはっきり見えたので今シーズンはこれでOKかな。
