Re: (ATMoB:Discuss) Barska Binoculars collimation procedure


Mario,

It was very easy to get decent alignment with the process on the
web site. The hardest part was getting a screwdriver small enough,
but any hardware store will have them. I just did it by looking out
my office window, and turning the two screws in small increments
until the image looked OK. It probably could use some fine adjusting,
but it was good enough for a decent hour of city observing.

Hi Matt.

I purchased one of those too and have the same problem 
with them.  They are severely out of alignment.

One of these days I'll get my butt off the couch and 
work may way up to the club house to try to get them 
fixed.

Does anyone in the list have any experience with bino 
aligments?  A few tips would be nice.

Thanks.
