Messier 46, 47

Messier 46, 47

This pair of open clusters in the constellation Puppis is located to the east and just above the brilliant star Sirius. While they almost look like companions, M46 is over 5,000 light years distant while M47 is much closer at about 1,500 ly. Adding interest to the field is the small planetary nebula NGC 2438 nestled in the lower part of M46 on the right. While it appears they are associated, the planetary is some 1,500 light years further away in the background. The field was viewed on February 12, 2012 at both 92x and 57x with Ethos 13mm and 21mm eyepieces. The view of the planetary was enhanced using an OIII filter.
