M46 and NGC 2438

A fainter and smaller open cluster than M47 but just as attractive. This object has a slight condensation with many outliners and there is a lot of stars of similar brightness approx mv 9-10. In the north part of the cluster there is a small but conspic planetery nebula (NGC 2438). With an OIII filter the planetery shows more detail. The Planetery is slightly elongated E-W and it's brighest at North.

I will check it out again tonight, see if the Planetery neb is as easy in the 120mm refractor
