Now that my processing skill has improved marginally I thought I'd re-do a couple of old images (no chance to do any imaging lately anyway).
This is a reprocess of a 50 mm f1.7 lens image of the Southern Cross and Coal Sack. Stacked 7 x 30 second exposures at ISO 1600 using the Pentax K-5 DSLR.
The original effort had really bad CA which I've now managed to (partially) process out. The lens is one I've had since my film-camera days back in the 1980s so not sure how to go about finding a lens-correction profile for it.
