The main reason for the images on a binocular drifting is that the muscles of the nahds and arms with which you hold a binocularhave an intrinsic tendency to have a backgroud tremor, and this is transmitted to the binocular which in turn causes the image to shake or drift. It is particularly worse if the binoculars are heavy or when the arms are tired after problonged viewing or if there is anxiety in the user.

There is no proven technique of holding the binocular to avoid this shaking nor are there medications to stop the tremoulousness which is a natural phenomenon. THere are binoculars that have in built image stabilisers but they are usually very expensive

I wonder if there are accessories one can attach fo the binocular to minmise or stop the shaking or driftinng of the image?
