    Fixing Rubber Eyecups back on

    Be very careful using super glue near optics. The fumes will damage the coatings. I prefer using contact adhesive. A thin film on the insides of the rubber cups and a thin film on the eyepieces. Wait until tacky then push together.

    Elinor 10x50 removing focus wheel

    There are two possibilities. There may be a screw up the middle of the centre column. Try a screw driver and see if you can feel a slot but your description of the fault makes that unlikely.

    How to modify binoculars for closer focus?

    The inner eyepiece tube/lenses can be modified a bit to bring the tube closer to the external eye lenses. Enough to make a difference without affecting the infinity focus ( for most people ).

    Binocular eyepiece repair

    In photo 4 you can see a shiny silver scratch on the right eyepiece. This shows where one of the grub screws made contact with the tube that holds the lenses but then slipped and made the mark. You should find two more around the circumference.

Look at the the piece in photo 3 and locate the three tiny grub screws. It is these that secure photo 3 to the top of photo 2. You will...
