The Leo II Dwarf Galaxy (しし座の2番目の矮小銀河)PGC34176
A very faint and dark dwarf galaxy.
A few years ago I photographed the LEO I dwarf galaxy just north of Regulus, and although it was dark, but it was dense enough to be reasonably visible.
LEO II looks like a faint open cluster with an exposure of about 2 hours.
It looks like it has to be taken in a good sky.

すごく淡く暗い矮小銀河。
数年前にRegulusのすぐ北にあるLEO I 矮小銀河を撮影したことがあるが、それは暗くはあったが、密度がありそこそこ見ることができた。
LEO IIは2時間程度の露出ではまるで淡い散開星団のようだ。
良い空で撮らないとダメっぽいな。
