How do I coallimate a Sakura 10-90x50 binos?

[lulaz]

Is there anyway? it is very out of aling, and I can't find the screws to turn and coallimate... does they exist?

Thanks in advance!

I'd leave binos alone unless you really know what your doing. I have never done it but I know from other peoples experiences its a hard one to do.

Hi lulaz, as post #2 says, it's not easy.

But if the bins are so bad as to be unusable, then the following link may help :

Please go carefully !!

Sorry to be a "wet blanket" but quite honestly zoom binoculars with a range of 10x-90x and only 50mm aperture, are not particularly suitable for astro work. It's almost a lost cause even trying to collimated much lower power zooms and they never keep it for long. My advice would be to spend any money that professional help would cost on a pair of standard 10x50's, the type often offered in the Lidl/Aldi shops at around £15 would be infinitely better.
