The Guitar Galaxy and Leo A Galaxy Cluster (ギター銀河とLeo A 銀河団) ARP 105,Abell 1185

When I started shooting, I targeted ARP105, which is a vertically colliding galaxy to the east of the center, but it was quite faint and underexposed, resulting in a crumbling galaxy, so it fit perfectly in the FOV during processing. Leo A galaxy cluster is also included. This kind of approach is really bad.
撮影開始時は中央の東にある銀河が縦長に衝突しているARP105をTargetにしていたが、かなり淡く、露出も足りずボロボロの銀河になってしまったので、Processing時にFOVにすっぽり収まっていたLeo A銀河団も含めた。こういうやり方は本当はダメなんだよな。
