Farbege Egg Galaxy In Ursa Major (NGC4805)
A dwarf bar spiral galaxy located in Ursa Major.
Its name seems to originate from the fact that over 200 years ago, jewel-encrusted ornaments called "Easter Eggs" were made for kings and nobles, and among them, those made by Farbege of Russia were particularly famous, hence the name.
In other words, its egg shape is quite striking.
I started photographing it thinking it resembled the Whale Galaxy, but during the shoot, I found out it was a dwarf galaxy.
I've photographed many dwarf galaxies, but I've never photographed the LMC or SMC, so this was the first time I'd seen such a bright dwarf galaxy, and I was surprised by its brightness. It belongs to the M81 Cluster, like M81 and M82.

おおぐま座にある矮小棒渦巻銀河
名前の由来は、200年以上前に皇帝のイースタ・エッグと呼ばれる宝石を散りばめた装飾品が王様や貴族向けに作られていて、なかでもロシアのFarbege氏が作ったものが有名でこの名前がつけられたようだ。
つまり卵の形が印象的なんだろうな。
私はくじら銀河に似た銀河だなと思い撮影を始めたが、撮影中に調べたら矮小銀河だということがわかった。
色々な矮小銀河を撮影してきたが、LMCもSMCも撮影したことがないので、こんなに明るい矮小銀河は初めてで、その明るさに驚いた。M81やM82と同様M81銀河団に属しているとのこと。
