Description

In addition to the open clusters Messier 46, Messier 47 and NGC 2433, this image also captured two planetary nebula - NGC 2438 and Minkowski 1-18. NGC 2438 is seen in the wide field view above as the blue dot superimposed on the Messier 46 cluster and is shown in more detail in the full resolution image. The tiny planetary nebula Minkowski 1-18 is seen as the faint red tinged dot a little bit above the NGC 2438 PN in the full resolution image.

This is an RGB image with 30 minutes exposure time for each channel.

The photons for this image were collected at Shelter Valley, San Diego County, California, USA.
