A. Bright Spots
a bright spot is a small, non-uniform, bright area that may flicker or
appear constant (Figure 3-3).
not all bright spots make the atn Mars rejectable. Cup your hand
over the lenses to block out all light. If the bright spot remains, re-
turn the atn Mars. Bright spots usually go away when the light is
blocked out. Make sure any bright spot is not simply a bright area
in the scene you are viewing. Bright spots are acceptable if they
do not interfere with the ability to view the outside scene.
B. Emission points
a steady or fluctuating pinpoint of bright light in the image area
and does not go away when all light is blocked from the objec-
tive lenses of the scope (Figure 3-3). the position of an emission
point within the image area does not move. not all emission points
make the atn Mars rejectable. Make sure any emission point is
not simply a point light source in the scene you are viewing. emis-
sion points are acceptable if they do not interfere with the usability
of the device.
