The adapter has a 1/4 inch thread and must be mounted on a stable 3-leg tripod. (aluminium of ash wood) My light Manfroto befree tripod Sony-Fotoaparates or Videorekordes goes without problems, the Feldstcher is too heavy
and the image in the eyepiece is too shaky.
In this case, please contact our customer service directly so that the problem can be checked.

Hi, I haven't had this problem yet. I mainly use it to observe the moon, but I don't have a double image. Only the focussing is inaccurate and the eyepieces need to be adjusted.
