First trials were done this afternoon to explore camera CN with an artificial horizon. The first problem was the halving of an already limited field of view. This restricts observations to less than 12 degrees of altitude for the 50mm lens used. Wind was a bit of a problem. To get a sharp steady reflected image it was necessary to wait for a lull then snap the shot. Camera settings: f22, 1/4000sec., ISO 100, infinite focus, no filters. All results came in better than 2'. During early twilight Venus was captured with camera settings: f2, 1/80 sec., ISO 1600, infinite focus, no filters. Results came in better than 2' even though Venus showed as a fat 5' fuzzy blob.
