About this object

This is an image of the small planetary nebula NGC 2346 in the constellation Monoceros. NGC 2346 is sometimes called the Butterfly Nebula and the Hourglass Nebula. This object is pretty small at 1x3 arcmin so I imaged this using 1x1 binning at .64 arcsec/pixel resolution. The image above is only a very small crop of a much larger field of view. The image is also rotated and north is to the right. A larger field of view can be seen by clicking the image above. A lot has been written about NGC 2346 and Hubble has imaged it. Here is a link and explanation of the Hubble data.
NGC 2346 has a bipolar shape, similar to many other planetary nebula. It also has a bluish core indicative of OIII emission. The central star is actually a double although at my resolution its impossible to resolve. This object was imaged under fairly dark skies at Starry Night Ranch near Okeechobee Florida.
