The Twinkling Comet Cluster (双子座のキラキラ彗星星団)NGC 2420

A very sober star cluster.
とても地味な星団。

It is an open cluster near the right arm of Pollux in Gemini. The number of stars is about 100, which is not a nice star cluster, but I was attracted to the name of The Twinkling Comet and wanted to see it.
If you observe Gemini with a super wide-angle telescope or binoculars, it will appear as a faint point, and it seems that it looks like a comet, so it seems that this name was given.
ふたご座のPolluxの右腕のあたりにあるOpen Clusterである。星の数は100個程度と決して見栄えのす星団ではないが、The Twinkling Cometの名前に惹かれて見たくなった。
きっと超広角望遠鏡Or双眼鏡でふたご座を観測すると淡い点として写り、それが彗星の様に見えるためにこの名がついたものと思われる。
