Description

Imaged over three nights from a dark sky location in the Western Darling Downs in South East Queensland, Australia and in Laidley Creek West in this same region. The object only reaches 20 degrees maximum altitude when it crosses the meridian at this location. I have added monochrome Ha to my final image.
