The Great Barred Spiral Galaxy (禁じられた大スパイラル銀河) NGC1365,NGC1386,NGC1369
"Barred galaxy", what mean?
Last year's solo shooting ended halfway, so I was shooting solo this time as well.
I knew that two galaxies would be close enough to the east, but I intended to crop them, so I was shooting around NGC1365.
When I looked at the picture after stacking, I could not crop this small galaxy because it showed more eastern galaxy than I expected.
In such a case, it would have been better to shoot with a field of view that would bring smaller galaxies closer to the center.

”禁じられた銀河”、、、、、なんのこっちゃ。
昨年単体撮影が中途半端に終わってしまっていたので、今回も単体での撮影をしていた。
東にギリギリ2つの銀河が入り込むのは知っていたがCropするつもりで、NGC1365を中心に撮影していた。
Stackが終わった写真を見ると、予想以上に東の銀河が写っていて、この小さな銀河をCropできなかった。
こんなことならもっと小さな銀河が中心よりに来るような写野で撮れば良かった。
