Description

My attemp to capture M46 while preserving star colors in bright suburban skies. This is an HDR combination of 60 second and 8 second exposures which helped to preserve the cores of some of the brigher stars.

Planetary Nebula NGC 2438 is present near the center of the image, but I got a surprise bonus: M 1-18 can be seen to the right of NGC 2438. It is a 14th magnitude planetary nebula that shows up as a dull red spot. At first I thought it might be an internal reflection from HR 2959 (bright/large orange-red star in the lower left).
