I have just purchased a set of the above binos and have found the collmation if out vertically. I got themfrom Sirius Optics after a long delay. A internet search reveled that orion has not got a good reputation for aftersale service. Can anyone suggest the best way foward. I don't really want to pull them apart and i do not know where to get them repaired.For the price,youwould thinkthe quality would be better.
they are big binos, prob send them back to sirius if you can -they will still be under warranty, problem with a big instrument like them, once you open them up you can see they will get knocked out of place as the prisms are held in by push/pull screws with too much plastic.
the chinese binos use the purchaser as instrument tester to an extent..can't be totally avoided except buying higher build quality items -such as the 15x70 MB/ultra series, in 25x100 there are no real standout performers under $1000
if you want you cna send them to rogers optics, in sydney
The majority of binoculars that are not junk level products have collimation
screws tucked away under the rubber or other material covering. If it is
possible, try lifting the covering around the edges and you might uncover said screws; otherwise I guess you'll have to return them under warranty.

Your first step is to talk to the retailer if they are new and under warranty. They have an obligation to correct the defect as it sounds as though they are not fit for purpose as sold to you. Don't attempt any form of dismantling or corrective action that may void your warranty.

Sorry to hear that the binoculars are out of collimation, when we got them from orion they told us they should be sent out in large shipping boxes specifically to avoid this kind of problem. The cost of getting them air freighted out to us from orion was nearly double what it would normally have been. It seems this was all in vain.
However, we can fix the problem.
We have someone who is local to us who fixes exactly this kind of problem for us and does so professionally.
Send them back down to us and we'll get them collimated for you and send them back up, it should only take a few days for us to get them collimated.
I had a pair of Zhumhell 25x100,s that arrived slightly out as well and found that there are two small screws on each barrell at the eyepiece end , you have to peel the rubber back to expose them .
It is easy to collimate the prisim bu turning either screw as the side one moves the image sideways and the top one moves the image up and down.
Its much easier if the binoculars are mounted solidly on something and once done mine never needed touching again and gave awesome views when mounted of the sky , I am positive that the Orion and Zhumhell,s are the same , just use a teaspoon handle to lift the rubber to look for the small recessed screws , it won't hurt them if you take your time .
On more thing. , you should only have to touch one side. , the one that is out .
First off I want to thank Sirrus Optics for their offer to swap the binos for a collimated set. As I told them I travel a lot so it would be an advantage to be able to check the set up at anytime. I set the collimation using the advise given and got them pretty close. I found a site yesterday showing how to use the sun to do an accurate collimation so have built the stand and will report back on the results. It is a very comprehensive and detailed site.

This is the bench I built as per the previous post. I mounted it on my old meade lx200 mount. It makes it a lot easier to chase the moving sun. Will check the collimation tonight subject to clear weather.
Sorry I have not responded sooner but have been busy. The rig worked perfectly. When i used the binos at night, it only required an eight ofa turn on one screw to be spot on. Very pleased with the result. Have also manufactured a solar filter andwatched sunspots for hours. Am now very pleased with the results
