Southern Sky with PS a530
It was new moon and a perfectly dark sky at Angra Dos Reis, about 200 miles west of Rio de Janeiros, with an unobstructed view to the South from my hotel room on the beach. Coming on a vaccation from Los Angeles this was a rare and unexpected high quality sight of the southern sky. So I got my Canon a530 out, clamped it to the balcony and took 25 shots in CMDK sequence mode at in iso200 at 15 seconds each in wide angle. Registered and stacked using IRIS. This produced a spectacular 50 x 35 degree field of view. The attached cropped picture covers only 25 x 17 degree. The prominent star on the left is alpha Centaurus, the southern cross is in the upper right. The coal sack is visible and the faintest stars are +9.5. Not bad with a Canon a530 (f=5.8mm 2 mm aperture) and without a tracking tripod.
If you took a shot similar to mine with a Nikon or Canon DSLR and a 28 mm lens or similar, please post it, so that we all can see what I missed by not lugging my Nikon D40 on this trip.
Enjoy.
