New binocs , problem?

[Cheychi]

Ok so the new binocs arrived this morning.

One issue I'm having is that when viewing if I move my eyes whilst looking through them I see what looks like black disc shapes moving in the view from either side, depending on eye movement.

Any ideas anyone?

Do you have the Inter Pupilry Distance (IPD) set right ?

When looking through bins you should see a circular image not whats depicted on tv/movies of a binocular image

[Cheychi]

Yes I've adjusted that but it's still happening????

[Stormbringer]

what make and size bins are they ?

Sounds like the infamous "kidney bean" effect, usually caused by not having your eyes accurately on the exit pupils.  Takes a bit of practice to get it right and some eyepieces are more prone than others.   😀

That's a new one on me peter but makes sense

Try varying the clearance between your eyes and the eyepieces, you should be able to find an optimum position.  If the eyepieces have twist up/down facility this helps to keep your eyes in the right place.     🙂

They're 20x80s

Thanks Peter 😀😀

[Stormbringer]

Observation bins take a wee bit of getting use to

[Peter Drew]

Ah,  20x80's,  these are going to be difficult to hold steady enough to get your eyes in the best position.  If/when you mount them it will become easier.        🙂

you may find resting your eyebrows on the eye cups so you can get your pupils a bit further back and braced helps. I have a pair of binoculars that I am sure I will love when I am old and need to wear glasses, but currently frustrate me a lot as it’s hard to find the optimum eye spacing so I see the full field most easily.

Even when things are adjusted well you may find you still get blackouts when looking to the left/right hand side, your pupils are not now lines up with the exit pupils, nothing you can do about this.

hope you find a way to get them working
