| Description | (description
supplied by Sakib Rasool) PN
G237.9-07.2 is one of 1200
planetary nebulae discovered in
the MASH (Macquarie/AAO/Strasbourg
Ha) survey. It has a size
of 11x10 arcminutes and is
currently classified as a
possible planetary nebula due to
a lack of spectra. However it
responds reasonably well to
imaging with both Ha and OIII
emission present.
