Description

IPHASX J022045.0+631134 is a small (30 arc-second) but bright planetary nebula (PN) discovered in 2011. It is dwarfed by the massive supernova remnant (SNR) HB 3 (G132.7 + 1.3) which itself was first discovered as a radio source in 1953. The scale of HB 3 can be seen in an image by Nicolas Outters where the PN can be seen in the extreme top left corner of his image http://outters.fr/wp/?p=2260.

The PN is challenging to image not only because of its size, but also because of a large star that obscures the north east end of the nebula.

This is a mosaic of two panels so that more of the of the SNR can be seen.
