I visited Leyburn for the first time last night with a few friends from IIS.
Seeing wasn't the greatest and the fog + airglow was pretty thick, but thanks to the cooler weather I finally managed to get more signal than noise on my longer exposure tracked DSLR shots (click on links for larger versions):
1. Scorpius and the Milky Way
: 19x 181 sec (57 mins total), f/2.8, ISO 800 subs taken with a stock Canon 5DmkII + 24 mm f/1.4L II mounted on an Astrotrac.
2. Corona Australis
: 11x 181 sec (33 mins total), f/4, ISO 1600 subs taken with a stock Canon 5DmkII + 100 mm f/2.8L IS Macro mounted on an Astrotrac. This one definitely needed more data.
3. Crux and Lambda Centauri Nebula
: 15x 182 sec (45 mins total), f/4, ISO 1600 subs taken with a stock Canon 5DmkII + 100 mm f/2.8L IS Macro mounted on an Astrotrac.
All shots stacked in DSS (lights only - no darks/flats/bias) and processed with PS CS5 and GradientXTerminator. Thanks for looking!
