Description

This object, also known as IC 1454, is a rarely imaged planetary nebula located 14,000 light years away in the constellation of Cepheus at a declination of +80 degrees. The PN spans 40 arc-seconds in our apparent view, which corresponds to a diameter of almost 3 light years.

This PN is the most northern of all of the Abell PNs. Very little information exists on this object. I see no central star. The signal is primarily OIII, but towards the inner region you can see some red tones which indicate stronger Ha. Its overall bluish donut shape reminds me of IC 5148.

This is the first image of this object on Astrobin.
