Upon casting this spell the wizard is able to see anything within his normal range of sight as if he were much closer... close enough to see even the smallest details. The effect is similar to that of looking through a field glass, except it is more precise and clear. The caster can also angle his view to get a bird's eye view affect. The height of elevation can be up to 10 yards per level straight up.
This spell does not confer the ability to see things outside the caster's normal range of vision, just to see those things that are within his range of vision much better. This spell in no way confers infravision or X-ray vision of any sort.
The material component of this spell is the feather from an eagle.
