Finally I got to try my D5100 with real Aurora. While not that spectacular to the eye this time, it is always fascinating how a DSLR captures colors that the eye cannot see as clearly in low light. Taken last night at Ballaine lake on my way skiing home from work. A road passes by the lake and causes the light pollution with sodium vapor lamps. 10.5mm at f/3.2, exposure 15 seconds ISO 800.
