Description

This object, also known as NGC 7076, is a rarely imaged tiny planetary nebula located 6000 light years away in the constellation of Cepheus at a declination of +63 degrees. This nebula spans 1 arc-minute in our apparent view, which corresponds to a diameter of 1.7 light years. Not much has been written or researched about this object.

Ignoring the 2 foreground stars in the nebula's line of sight, the bluish central star is clearly visible. The nebula appears slightly squashed due to impact from the ISM, which particularly has affected the inner bright torus on the right side. The nebula appears slightly bipolar with an axis pointed up and to the right. The nebula signal is predominently OIII, although enough Ha is present in the torus area to give the inner ring some definition.
