Barska 42mm red dot scope works as intended - Barska 42mm Red Dot Scope AC10330 - 1x42 Red Dot Sight w/ 5 MOA Reticle

This scope is used on a Panasonic camera for astrophotography as a pointer. The red dot intensity has enough range for daytime on the higher settings and nighttime at the lower two settings. Very low parallax problem so aiming good. It also came with a battery installed and another spare.
Pros: Works well. Good value for the price.
Cons: None
