M46,NGC2438はとも座の冬の天の川にありますが、結構低い位置なので透明度の良い時でないと良く見えない。透明度が良かった今夜のＮＧＣ2438（惑星状星雲）は45㎝眼視（180倍）で円周のピンク色のが分かりました。ただ気流はブアブアでした。
M46 and NGC2438 are located in the winter Milky Way in Pup, but they are quite low and cannot be seen unless the transparency is good. Tonight’s NGC2438 (planetary nebula), which had good transparency, was found to be pink around the circumference by visual observation at 45 ° (180x). Seeing conition was poor.
