Elinor 10x50 removing focus wheel (1 Viewer)

[fairgrace]

Hi everybody,
I'm new to this forum but I wo der if anybody can help me with this issue. I need to take the two halves of my Elinor 10x50 binocs apart as the focus wheel never stops to turn and I cannot make anything really into focus. The only way I manage to really focus is byanually extending the eye pieces and then use the focus wheel to bring them back a bit and thus into focus.
I've successfully removed the caps and screws both ends of the focus wheel, but then I'm stuck as there are no more visible screws but the focus screw is not coming off.
I've peeled back some of the rubber on the wheel but can only see a notch in the casing with no screws.
Any advice extewmely welcomed.

Many thanks in advance,
Lucia
P.S. apologies for sandy photo but we live on a boat at the moment...

You will need some help, so check with the mfr. to see if you can send it in for repair.

A deep clean to remove the grit and sand might be a good first step.

Firstly, the Ostara Elinor 10x50 is not made by Zeiss.
However, it is reputed to be "waterproof" - if a £199.99 bino can be waterproof. So I'm going along with Mr. Holdsworth and recommend a good wash in the shower. Possibly even a soak in folded position with the focus wheel/hinge submerged in an attempt to penetrate the gunk.

I’m not sure taking it apart is your all-time best idea.

Good luck if you do.

Can't see how it can have a "sealed, waterproof and nitrogen filled body".

It is a centre focus porro-prism and has to let air in somehow as it is being focussed and the eyepieces are moving up and down.

True, but at least these three dealers promise that the body is fully waterproof.
One
Two
Three

Since I have no personal experience of these I can only relay such information as is given and I did put waterproof in inverted commas.

Magical O rings?

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.
Or there may be a screw under the rubber covering the focus wheel. if there is then it engages with the
focus shaft and slides up and down an angled slot but as the focus wheel never stops turning
then that is also unlikely..
So first check that the rubber covering on the focus wheel is attached to the wheel. I have known
the cover to have grease under it so it just slips round without gripping. The is an easy fix.
Slit it vertically, remove it, clean it and the wheel and re-fix.
If it is water proof then be careful as there should be a seal around the eyepieces to the body.
Some Zeiss did have that arrangement.

Yes, one wonders how Swarovski managed just that with their Habichts since 1984.
