Dana Patchick and I discovered this nebula when searching for potential undiscovered planetary nebulae. It had a promising hot star which triggered the possibility of this being an attractive, large PN. However after shooting 8 hours with an OIII filter we found no OIII emission. Thus we concluded that it was a 'failed' PN - but a nice example of ionised ISM. Its curious morphology led me to name it The Rocking Chair Nebula.
