The Starfish Cluster (Messier 38)
The other starfish cluster is M38. I couldn't quite get the colors of the stars to come out, so the exposure ended up lasting two hours.
Another name for this cluster is the "Letter π" cluster.
Both names are a bit tricky.

もう一つのStarfish星団はM38。なかなか星の色が出なくて結局2時間の露出になってしまった。
この星団もう一つの名前が”πの字”星団。
どちらの名前の微妙だな〜。
