The Lemon slice Nebula In Camelopardalis (IC3568 )

A planetary nebula in the constellation Camelopardalis.

A nebula I've wanted to photograph for several years.
The lemon slice pattern is within the inner edge, but it's too small to really look like a lemon.
A complete failure.

きりん座にある惑星状星雲

数年前から撮りたっかた星雲。
レモン・スライスの模様は内側の縁の中にあるが、小さくて全然レモンにならなかった。
大失敗。
