Many thanks, Patrick. Does it make sense to multiply the two to arrive at the total number of square arc-minutes?

Going from the horizon (assuming a flat horizon) to the zenith and back down to the opposite horizon would be 180 degrees. Multiply times 60 (60 arc minutes per degree) = 10,800 arc minutes. But measuring around the horizon is 360 degree or 21,600 arc minutes. patrick On 08 Feb 2009, at 22:29, Joe Bauman wrote:
Hi, Can anybody tell me right off-hand how many arc-minutes the night sky is? Thanks, Joe
