Hi Jackie,
I have the same problem. Day time terrestrial viewing is fine but trying to view a point source of light, such as a star or planet, produces two images. The gap between the two bright objects is relatively small for me in low power binoculars and with a little concentration I can merge the two images. However, the gap is significant and a real problem using binoviewers on a telescope. No matter how hard I try I am unable to successfully merge the two images. At medium power, I have found that I can merge the two images of the moon but my eyes soon tire. If I then concentrate on an individual crater, the two images quickly diverge again.
I mentioned this to my optometrist. After a few measurements and tests, he confirmed that I have a slight muscular misalignment of my eyes which is sufficient to prevent my brain merging the two images. There is nothing that I can do about it.
So, I have reluctantly sold my binoviewer and matching eyepieces and have resigned myself to mono observing.

Cheers

Steve.

They are just fine during the day, looking at general scenery, which is crystal clear, and I think I have properly culminated them. But when looking at the heavens at night, I see 2 of each thing I look at! I don't know if maybe it is just my eyes/brain not processing those little pinpoints of light very well.
