This is a pvs14. When viewing in dark conditions with the gain turned up there are two bright spots that appear. Turning the gain down causes them to fade and disappear. They appear in the same place each time. Also, If I cover the objective I can make them appear by turning up the gain.

Are these emission points?

do they remain after the unit is powered off?

Do you they appear bright when in complete darkness WITH the daylight cover on?

No they fade out with e objective covered. They also do not remain lit when the power is turned off.

They pretty much only appear in really dark condition with the gain way up. I did notice with the gain at a normal setting I can see small dark spots where the bright spots would appear. Perhaps this is just a minor defect in the tube? It does not effect viewing in a large way. I just want to know if I should expect them to get worse over time.

ETA- they disappear completely when going from very dark conditions to brighter conditions.

A steady or fluctuating pinpoint of bright light in the image area that does not go away when all light is blocked from the objective lens. The position of an emission point within the field of view will not move. If an emission point disappears or is only faintly visible when viewing under brighter nighttime conditions, it is not indicative of a problem. If the emission point remains bright under all lighting conditions, the system needs to be repaired. Do not confuse an emission point with a point of light source in the scene being viewed.
