Why is it when I view a flying plane or a flying bird with my binoculars, I see the plane/bird with a double "ghost" image?

Double Ghost Image

The ghost image could be created by the speed of the object, the extra light from the sun reflecting on any internal metal parts of the binoculars which can be coated to reduce glare reflection.

A strong magnification, such as 10x, can be affected by handshake and could possibly create ghost images or optic flare.

Always check focus and adjust the center wheel first. Make allowance for distance, speed and light. A good cleaning may also be in order.

How do you prevent a double image in binoculars?

Double Image

Preventing a double image from showing up on your binoculars could be as simple as bringing the barrels or tubes closer together if the binoculars are hinged. Also, it could be a focus problem due to the barrels being out of alignment which can be fixed in most cases.

Some binoculars just need the old fashioned remedy of closing one eye to see one of the image and other binoculars have such high magnification that seeing two of the same image through each barrel is normal.
