Olympus DPS I 10x50 - Collimation issue?

[Dark Knight Gazer]

Hi there,

Just looking for some advice regarding the Olympus DPS I 10x50 binoculars.

When looking at the Moon or terrestrial objects, they perform great.

However...

When looking at stars (any star really) there seems to be a double image of the star.  Could this be a collimation issue?  If so, how would I go about correcting it?  I have adjusted the focus and the dioptic correction wheel on the eyepiece - with no joy.  

The left hand (when holding them to your eyes) lens tube does rotate, is this natural?!

Any help/advice would be much appreciated.

Thanks,
DKG

DKG.......Hi, did you get sorted with your binoculars

Hey Charic,

I returned the Olympus - no quibbles. Then ordered the below from Harrison Telescopes for around £5 cheaper. Although the FOV is slightly narrower, the pefermance is greater.
