Binoculars - field of view

[brian fleming <>]

Sometimes quoted as "Metres at 100 metres" (or yards);  sometimes as 
degrees..
Some spreadsheet work came up with:

Degrees     metres at 1000
2                 35
3                 52
4                 70
5                 87
6                 105
7                 122
8                 140
