Quote:Can you try and move a star to the edge of the field in both sides and up+down in order to see if the two images show the same? You can also do this during the daytime, with pretty much anything that has a sharp defined point/edge. If you can see something at the edge in one eyepiece and not the other, the binoviewer is out of collimation and merging will be very tricky and strenuous.
Quote:You can collimate it by loosening the screws that hold the eyepiece holder to the body itself and moving it around. This requires a fair bit of patience and trial and error. The manual should also cover this if I recall correctly. But check that the fields line up first.
Quote:Merging is also easier with eyepieces that have longer focal lengths. Do you have a pair of 25 mm plossls? I am only using 18 and 25 mm eyepieces with mine and have largely given up on my 12 mm pair - I do use them for collimating the binoviewer though.
Quote:What I would do is make sure the images are lined up vertically and then experiment with the collimation screws left-right until you get a nice merge. You will know when they merge, the images just pop together into one image.
