The Eye Of Sauron Galaxy Galaxy (サウロンの目銀河) NGC 4151

Clear Sky for the first time in a while. Shooting the first target before the moon comes out.
I would like to see more of NGC4151's arms.
It is said to be the closest galaxy to Earth that has a supermassive black hole.
The name comes from Sauron, who appears in The Load Of The Rings.

The one in the northeast is NGC4156, and the one in the east is PGC38811.

久しぶりのClear Sky。月が出てくる前に初ターゲットの撮影。
名前の由来はThe Load Of The Ringsに登場するSauronからつけられてるそうだ。
