The PN51 is a Gen 2 night vision scope originally designed and fielded by the Soviet Union. This scope is from after the fall of the Soviet Union and is not marked with a hammer and sickle. This device is significantly stronger than the 1PN58 scope, though shares the same reticle and mostly the same controls (We have previously had a 1PN58 through the shop, so we say this from experience). The scope is a set 3.46x power. It has an adjustable focus, can have its elevation and windage adjusted easily and includes a day cover. This optic CAN be shot during the day with the cover on, but do ensure that if you are going to do this, you adjust the cover to be FULLY closed off to start, then one click at a time open it to the optimal level. It does have an auto-shutoff if overwhelmed, but this doesn’t mean the tube can’t still be damaged.
This unit has been converted for 9v battery usage, but this is easily reversible if you want to use original batteries (Where the hell did you find them anyways?).

They have compiled a lot of excellent info and broken it down in a psuedo user guide as well.

Below is a video with only a sliver of moon in a dark public park. The glare is coming from lights behind me, that is normal for night vision when viewing an area in extreme darkness with light behind you.
