StDr 29
An unusual likely planetary nebula discovered by my good friiends Xavier Strottner and Marcel Drechsler in 2020. It is notable because of its strange morphology with [OIII] and H-alpha emissions being non-concentric.
I would like to thank the Astronomical Society of Edinburgh for contributing some 17 hours of Ha data from their ASERO remote observatory in Norther Spain.
