Chaps my maths is failing me. What is the field of view of these 8x30 marked 393 ft @ 1000 yards: 7.6 degrees ?

Hi maico,

7.505 degrees.

However, the top two bright stars in Orion are about 7.55 degrees apart, so hand held it should just include these at the extreme edge. Because of slight hand movements and persistance of vision.
Not visible till after midnight but next month earlier.

But if the binocular is held very steadily they shouldn't both be seen at the same time, although edge stars are usually a mess.

Usually the field is less than marked but not always.

It is always best to measure things than rely on what is written on the binocular.
