The Little Pinwheel  Galaxy   (小さなピン・ホイール銀河) NGC3180

It turned into a lazy galaxy, and I thought it was going to the trash can. However, the 6.5th magnitude star (GP UMa) shining next to the galaxy became unbearable, so I decided to leave it.

なんともだらだらしたLazyな銀河になってしまい、ゴミ箱行きと思っていたが、隣で輝く6.5等星(GP UMa)が忍びなくなり、残すことにした。
