Sighting, how far from a scope should your eye be?

[Parabuteo]

This might be a silly question, but I'm still getting used to shooting with a scope.

Is there an accepted 'normal' distance for your eye to be from the scope? I ask because I find quite a difference when I'm say kneeling and aiming to when I'm prone on the ground.

I move my eye around until I have the clearest full view through, but find moving left/right/up/down even a small amount will blur out that side of the scope. I found that moving back a bit gives a clearer view but with a bit less tolerance of lateral movement.

Be grateful for any advice.

Basically, eye relief will change from scope to scope.

You should be able to see a full image edge to edge. If you cannot, or if you have a dark blurred surround to the image, eye relief is not correct.

You should find a point where you can move back and forth a little and the image remains correct, this is to allow for the fact that your head position will move slightly between positions.
