Description

This was a dark sky test of the D80A with the Ziess 135 APO. I took this quick series during a family gathering at a rented cabin in the Quebec Laurentians. I was only able to get 8 shots of 3 minutes. due to clouds. Also the lens was set at f4 I had wanted to have f2.

The unguided Adventurer was unable track the stars well enough for the camera lens combination. Each frame streaked 1-4 pixel with the majority around 3. I was able to correct using photo shop.

The uploaded imaged is sampled down to 33% of original.
