Description

Decided to show the cropped image.

I got two Messier objects for the price of one while taking this image under the nearly full moon. In the bottom left is M46 (NGC 2437) which is an open cluster in constellation of Puppis. M46 is about 5,500 light-years away and with approximately 500 stars and estimated to be 300 million years old. As a bonus, a planetary nebula NGC 2438 appears to lie within the cluster near its northern edge, but it is a foreground object and unrelated to the cluster. The 4.95 magnitude bright star in the bottom is 140 Pup. (source: wikipedia)
