[Atmob-discuss] Help with binoculars

[Neveu, Jean-Noel]

Thanks Michael,

I did in fact tried to play around with those screws but they seem to
control each image on the vertical plane.  I didn't see two images
getting closer to each other while adjusting those.  That is I still see
two images going up or down relative with each other as I adjust those
screws.  Am I doing something wrong?  Is that all you had to do to fix
yours?

Regards,

Pedro

I had the same problem with my Barska binoculars I purchased several
years ago.

Under the rubber armor there are two small adjustment screws, one on
each occular, which adjusts the tilt of the prisms in the two different
diagonal directions.
To turn the screws you'll need a flat head jeweler's screwdriver, i.e.
the kind of screwdriver used for adjusting eyeglasses.

I recommend putting the binoculars on a tripod, or other set up that
leave your hands free, aimed at a star or a distant terrestrial object
(such as a light on top of an antenna tower), and adjust the 2 screws
while looking through the binoculars until the what you see in each
occular is aligned with each other.

If you have 2 such screwdrivers could hold one in each hand and adjust
the 2 screws at the same time while looking through the binoculars.
