I accidentally knocked my binocular (carlton optic adlerblick 7x50) down from a table.
It lost its alignment, and now I clearly see double stars. The left side shows round exit pupil but the right side has cat eye shape.
First, I wanted to try the prism screws. They were so jammed that I break the tip of my jewelers flat head screw drive but they didn't turn.
I took of the retaining ring of both objectives which allowed the one of the objective lens be turned around its axis but the other lens couldn't be turned.
When I turn the objective lens nothing happens to the alignment of the bino and I see double stars in more or less the same location no matter how I turn the lens.
My question is: Does they have eccentric rings for alignment? Anyone has a clue or suggestion?
