Description

Another snapshot of the Southern reaches with the Veloce H8. The results weren't brilliant as some areas displayed significant defocusing aberration (basically toward the upper right side) which I found difficult to overcome even with BXT.

Guest appearance by a number of tiny PNs, the largest of which is Pk359-00.1 otherwise known as Hb 5 , left of center.
