The object is:
IRAS 05081-6855; or
SMP LMC 28
It is a planetary nebula in the LMC. [Humayun was correct in his guess!]
Anyone wanting to investigate 'odd' objects in their images should take the time to become familiar with the Aladin program of the Centre Donnees Stellaire. It is a simple executable downloadable from:
http://aladin.u-strasbg.fr/aladin.gml
which allows you to plot catalogue identifiers overlaying survey images, with tools to easily extract the catalogue info. There are versions for all platforms. For investigating what is on your images, it makes any commercial planetarium software a child's toy.
