I purchased a set of Celestron Upclose 20x50s. Arrived way out of collimation. Called the manufacturer who did not assist me with the issue, so I am glad I found your video! I could not find the secondary screws on inner sides of the barrels, but discovered that by adjusting the one on the top of the right barrel corrected horizontal collimation and on one the left side corrected vertical collimation. Regardless, thank you for this video. Educational and easy to understand your technique

Unfortunately This wont apply to other designs where the outer shell ( body ) is of solid construction. Where there is no obvious way to get into them , you have to send it to the manufacturer or distributor outlet They will simply verify the problem you state and replace them ( under warrenty as applicable ) I had such a pair out of colimation , I sent them off , they said there was a problem and sent me a new pair They work . But Im unsure if they seem slightly hazy compared to the last pair . But it might just be me. I have cleaned the lenses but I cant check the prisms. in case they have any contamination . They focus but somehow seem abit hazy when viewing
Cheers for the input. I do actually mention from 18 secs into the video that it applies only to binoculars with the rubber coating that can be peeled back. Different brands will have different warranty T&Cs as to whether collimation is included
Thank you so much for posting this. I dropped an inexpensive set of binoculars and was just about to give them to a charity shop with a note saying faulty. Now they are spot on, so we get to have one pair each again.
Hey there. Thank you for making these videos. I've bought binoculars (Maginon 8-24x50 with zoom). I used them a few times and stored them. Now when i want to use them again i see double image (i remember that they fell out of my hand one time). I hear somethi gobbling inside them. Screws for taking binoculars apart are hard accessible. What do you recommend for me to do now?
You do not need to take them apart for this. Plus doing so could create more issues if you do not know what you are doing. Not a fan of cheap zooms myself, but do order if any one wants any. If no luck I would recommend a set of 7x35 , 8x40, 7x70 or 10x50 budget binoculars. Fixed power will give a wider, brighter view
It would be helpful to know the impact of turning the screws left or right. And almost impossible to look through while making these adjustments. Tripod almost essential.
Thanks man. I bought my first binocular, a Celestron upclose 10-30X50. I was affraid I would have to send it back. Just by twisting the two upper screws you showed first I was able to fix the problem. Luckly this was enough, because the screws in the middle are not accesible. Cheers!
had some 20+ year old Celestron 7x50 that were a pain to use for the occasional use including stargazing. I used my Trico-machine astronomy mount to focus on a distant target and slowy adusted the double image in to one... and now its much better. Thank you. Couple more years of use out of these Bins...
Thank you ,I just got mine out after not using them for awhile. They were out of alinement. Followed your advice and all good now . Only had to use the right top screw and fixed. Thanks again.
I have just tried to collimate a pair of Ross, Solaross 9x35 bins and I have never seen a more cheaply made binocular, considering they were supposed to be quality made optics for their day, British made, the best we could make? they have gone in the Bin. Rubbish.
With binoculars like that, there are specialist repair companies out there. It just depends on how much you are willing to spend, and if you think it is worth it.
@@44messier There are only two in the UK, and the last time I had a pair cleaned by optrep they charged me nearly £100 and caused other problems to boot, no thanks. East coast Repairs are mainly a Zeiss repair shop and are booked solid, I don't like spending Lots of money on something that cost half as much to buy, I can see why British made Binoculars are worthless on the second-hand market, they are junk
Mine's only a cheap set. Thanks, I found it helpful. Got them more or less in line, but only roughly. Definitely an improvement though. It looks like on mine, the top screws are moving them up and down and the inside screws in and out.
Thanks for watching our channel. Have added a link towards the end of this video for you to click on. Though the first video shows less detail than this one
Thanks for your video! None of bino repair videos cover the possibility of fixing the alignment by rotating the front lens, the objective. It is mounted concentric so that moving it around it changes the optical center.
Hi, The problem I'm facing at the moment is that the right side eyepiece does not "rack in" far enough to focus when the left side is in focus. It's very frustrating. Is it possible that the collimation process can solve this issue? Thanks.
I had the same problem with a Chinese pair I just got from ebay, not to mention that they had been damaged in transit, resulting in the objective lens housing being cocked inward, and being cross-threaded! Anyway, I removed the rubber eye cups, and managed to adjust those lenses(they screw in or out) enough to fix the focus problem, so you might be able to do the same. You'll want to screw the left side out, and right side in. If you still can't get enough adjustment, maybe try swapping the objective lens housings over, then winding the eye piece lenses the opposite way(which is what I had to do!).
@@bensuhard Thanks for this. Unfortunately, I tried to take the eyepieces apart and messed that up big time. The bins are a total loss at this point. I'm going to be looking into some new ones...maybe even image stabilized. Very kind of you to offer your reply/suggestion. I appreciate it.
@@Geotubest Sorry to hear that! If they got set up correctly from the factory, we wouldn't have to risk damaging them! No problem for the reply, and maybe this'll help someone else reading through the comments. ...hoping your next binoculars are much better!
