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.

Looks like you're good to go but keep any eye on it just in case!
