Abell 29

Two red arcs take their trip across the southern sky

Unseen to all passers by

They were once a star that started to die

Surely that must be the first poem written about Abell 29 (PK244+12.1)? The nebula is hidden behind a grainy fog because it’s incredibly faint (14.3m/6x4’) and low down in the constellation of Pyxis the Mariner’s Compass. The grain is inherent in the camera. It took about half an hour’s worth of minute exposures at f/3 on the 20-inch with the modified Canon 1000D. Also a lot of teasing and tweaking was involved in the processing. I keep thinking I can see a hint of blue inside the red arcs. Hmm… a bit of an achievement from the UK, this one.
