I bought one of these very heavy binos. Used it a couple or 3 times on my Manfrotto t-pod. They are so heavy that, on the 4th or 5th nite, they stripped the threads off of the socket & it hit the pavement. This knocked both tubes out of alignment! At least the only external damage - to one tube - was an extremely small ding & a scratch or 2. STW - does anyone know of repair shops that do realignments? I'm in the Boston, MA area.

question

Trying to confirm that this item includes an interface to mount to a tripod?
Asked by: Jeff B.
Yes, it does. It is the metallic arm going down in the middle of the pic - and it is very easy to use. I use it with a rather study and high quality photo tripod - but still, when your eyes/forehead touches the eyepiece the image shakes a bit.I am very pleased with the binocular - BTW.

Can I see the rings of saturn and the bands on jupiter with 20x80?
Asked by: Anonymous
Absolutely. A 20x power binocular will easily show the rings of Saturn and bands of Jupiter along with moons of Jupiter. These are excellent binoculars also for viewing many other objects in the night sky.
