How to collimate Celestron Skymaster 15x70 binoculars

How to collimate your Celestron binoculars.

[@synfinatic]

Thanks! I can't believe how out of alignment my 15x70's were, but I was able to find the two screws and fix the collimation thanks to you. Really appreciate it.

[@robmurray2005]

No worries!

[@bobsnead4817]

Thank you very much for this video. It helped immensely. I might add that you do not have to take the hand grip off, but rather you can lift it up with a knife or other flat object to get to the screws -- now that you have shown us where they are!

[@adamrees400]

This is amazing and works perfect on my 20x80 skymasters. I didn't take off the grip I just used a small flat head screw driver to lift up the grip where the screw is. The grip isn't glued where the screws are and lifts up pretty easy. I was surprised at how easy this actually was. By doing this you are not damaging the grip or binoculars in any way. The screws have some sort of clear silicon type of covering that can be just dug out with the screw driver. Luckily I didn't have to do much playing around turning the screws to stop seeing double vision. I just had to turn both screws clockwise just a small fraction and the image was perfect. Thanks for this video it appears to be the only one around

[@robmurray2005]

Glad it could help mate! I couldn't find anything online and I took a shot in the dark. I have NO IDEA why manufacturers don't make this common knowledge. It is actually a positive feature to be able to adjust the collimation.

[@adamrees400]

+robmurray2005 they probably don't want you to know where the screws are so they can charge you for the service. Damn celestron!! again thanks for the video mate, up until yesterday I was experiencing bad double image and I really didn't want to send these off in the post anywhere, hassle etc. oh yeah and by the way where ever you live is beautiful!

[@willbranson3216]

Just throw them in the garbage and get a good pair.

[@casual-goy8811]

@@willbranson3216 what is the name of the "good pair"?

[@rayr1444]

Adam Globe Rees Yes. Do not tear off your grips! See video by Northern Optics.

[@BSS753]

I bought the Orion 15 x 70 binoculars that had the same problem adjusted them myself one little turn is all it took. Used a metal dental pick to loosen the rubber then pulled the rubber back to access the screws. Thanks for the video!!!!!!!!!

[@robmurray2005]

+Barry Shawkey I should have tried that before I just ripped the entire cover off!

[@chrispyn2000]

Agree with Bob below - very helpful. I was able to lift the grip without having to remove it, then a few turns and all was well. Thx again

[@UberCyberCats]

Nice! Thank you - you've helped me decide to get a pair of these. Seeing what they actually can do, and how to adjust them, helped ease my mind about making the purchase. Beautiful deck, by the way.

[@jamiegriggs9398]

Will give this a try, thanks for posting. Celestron used to have a lifetime warranty with these. However when I sent mine in because of the same issue they asked for receipt which I sent. When I got the new pair. No receipt sent with the new ones and they did the same thing. When I tried sending those in they said "no receipt, no warranty". They have been sitting in the case for several years now. Will try this, and if i cant fix it will put them in the garbage. Thanks for posting

[@casual-goy8811]

What happened?

[@zakaria600]

@@casual-goy8811 i think he threw himself in the garbage instead 😂

[@gsp6024]

Thank you for this video. Found a brand new skymaster 15x70 online for less than 50US they were way out of alignment. Now they are brand new and work perfectly. All the rubber is still in place as well

[@johanvanwinkel8590]

I had the same problem with my Orion 15 x 70 out the box. One lense up and one down. Thought my eyes went all bat shit. Supplier told me to ship it back but i must pay for postage. Shit on that. Saw bloke on youtube doing collimation, tried and it worked. Happiness. Just like u explained.

[@juliancaste3914]

today I colimated my celestron 20-100X70 , I had the doble image problem . I recomend start with the screws in the same posicion with a small adjust in the right and the left and repeat, you will see a better unique image. after continue with the others 2 screws in the other same posicion. this video really help me to fix my binoculars. in amazon's forum many persons purchase celestron's binoculars this this problem and don't have idea how to fix it

[@edanderson4263]

This is a great video. Thanks so much. I have the 15X70s and they are fine but it is good to know I can collimate them if I need to. and now that I know where the screws are I won't have to destroy the grips.

[@robmurray2005]

+Ed Anderson No probs glad you found it useful

[@HPJFilm]

Thank you, Now with my Skymaster 20x80 all is ok. I wonder why the supplier does not provide this information to the binoculars. Then he would not get so many negative comments and angry customers. Now I can enjoy the mountains without squinting. The Zugspitze is only once and not twice as before the adjustment.Greetings from Bavaria in Germany.

[@Kievlar]

I just ordered the same model from B&H. I’m hoping my item comes in good shape and will not need collimation. Crossing fingers!

[@casual-goy8811]

So what happned?

[@sajis79]

Thank you for this video. I got to know the position of the screws to adjust from this video. I could fix mine without breaking the rubber grip. Shipped product was utterly distorted. Now its 99% fine.

[@casual-goy8811]

What exactly did you do?

[@grantfryer407]

come to think of it i was looking at getting the 20x80's hopefully they won't have this problem

[@rayr1444]

Do not rip the rubber grips off and ruin your binoculars! There is a very easy method on another video for collimation with no damage and it takes only a minute or two. The video is posted on KZbin by Northern Optics and is 1 min, 11 seconds long. You will be glad you watched it.

[@andrewmcfayden6347]

Get some scrap soft leather, offcuts from a car seat upholsterer, cut to fit, then glue on. Do both sides so it matches.

[@kaje01]

Thank you for this. I am considering buying this binocular and discovered this issue. People say it's very difficult to fix but it looks like they're just too intimidated to get into it. I'll definitely be getting this pair. If you've still got your hand grip I'm sure you can find a good glue to stick it back on with. I would avoid anything really permanent... might be cool to drill some holes in the rubber so you don't have to remove them again?

[@robmurray2005]

That's a good idea now that we know where they are. Might be able to probe around and find the indent and then lift up that tiny little flap. I was about to throw them out however so it was last resort stuff to rip the whole grip off

[@kaje01]

Actually yeah I think you are supposed to do that. I just tore it off like the guy in the video. Still have it dangling actually, it doesn't bother me. By the way, THESE THINGS WORK GREAT if anybody is thinking of getting them. I definitely do not regret my purchase, you can see a lot with them.

[@nosedigger94]

Lol, I thought you were saying dick then I finally heard deck.

[@lilfire4332]

Omg thank you so much man your my hero 🤣🤣 I done that and it worked and when it’s good just superglue them back on that’s what I did

[@garyberger]

Thank you Rob! I was able to perfectly collimate my 15x70s following your instructions.

[@pureflamezz1818]

Thanks altho I think everybody this guy has passed away looking at comments on his first video either way cant thank you enough. I thought my shits were broken with no fix. I started getting the double vision issue been adjusting and I have the double vision gone now although still getting visual flare but its night time so I will continue tweeking them in the day time to get them perfected had to rip grips off though cos couldnt move the screw and get the pressure on it these screws are tiny

[@nikhilmenda2983]

Thank you so much my dude. I love you so much for uploading this!

[@scyz2807]

What I'm wondering is - Which screw adjusts the vertical alignment? You say you can do both, but you don't say what screw does what. I know that the top screw near the eye piece adjusted the horizontal, by my BIG problem is vertical misalignment. Since there are two other screws (one that is harder to get to) it would be nice to know the correct one that I need to adjust.

[@iangray7410]

Thanks, man. Sure appreciate your surgeries. I am in Nashville TN with a pair of Celestron 25 x 70 binocs and hope to see the stars come into one single image through these tatty lenses. Question is, did you figure out how to remove the skin to get at the adjuster screws without damaging the grips ? Cheers, mate. Heave another shrimp on the barbie for me, bonk your Sheila senseless and listen to Claire Lynch Bluegrass music (and not just because she's my wife but because we have taste in things that work).

[@casual-goy8811]

How did it go?

[@samihussain4969]

I think if we just cut the rubber half in circle over the screw would be better because we can cover that screw and if needed again you can just lift that small piece of rubber and play with the screw. Do not cut rubber completely in circle just half of circle (round shape the size of screw head but half) so it stay back on screw.

[@juliancaste3914]

great info !! I have the colimation problem. I will fix my binoculars whit this solution

[@robmurray2005]

julian andres castellanos Hernandez Good to hear! I only put this up because they are one of the most popular binoculars in the world and no-one anywhere could tell me how to collimate them. I know its a crappy video but glad you found it useful

[@XZAYLO]

AH THANKS so much! have the same binoculars and i almost went out to find a professional to fix it for an arm and leg!

[@robmurray2005]

No problem glad I could help!

[@benjaminzavala3358]

i dropped my skynasters last night. i need to collimate them now because im seeing double. i see you removed the grip on the right. is there also screws under the other grip?

[@robmurray2005]

+benjamin zavala Thats a very good question I have no idea! Maybe you can take a look and report back? I managed to fix them just by peeling off the right side

[@benjaminzavala3358]

yes there is. just use a butter knife to lift the grip no need to completely remove it. i couldn't tell if its collimated because im trying to test it on a star but this crappy chicago weather isn't cooperating

[@casual-goy8811]

@@benjaminzavala3358 so what happened, did u fix them, and how?

[@dschenk952]

Thanks for posting this. I am going to fix this myself rather than engage the folks at Celestron for a warranty repair. Do you recall which screw adjusted the horizontal and which adjusted the vertical?

[@robmurray2005]

+Don Schenk No - Im sorry I cant remember which one was which. Good luck with the repair!

[@dschenk952]

+robmurray2005 Thanks for replying. Oddly enough after purchasing a couple of other brands of 15X70 binoculars and finding them terribly out of collimation, I bought a pair of Celestrons which are the lowest price of the group, and when the arrived they were perfect in optical alignment. I think I'll wait until I drop them a couple of times and misalign them before I peel the covers off. :)

[@estebanri3009]

hey guys you do not have to completely peel it off, with a flat head screwdriver just lift the part where the screw is, it might be a little uncomfortable but it keeps them in better shape!

[@Hazzafication777]

Hey mate, cheers for the video! Ive been looking at getting a pair of these for a while but was hesitant because of the collimation issues I've read about on the cheaper celestrons, but if it's as simple as a few screws and reseating the housing thats really no dramas! If you were looking for name brand scopes in the future for a decent price but Aussie seller to avoid those exorbitant postage fees try Ozscopes, they're pretty friendly and have a great customer service rep. BTW what tripod is that? Looks stable enough and a hell of a lot more portable than my steel azimuth telescope tripod I was going to adapt to binos! +1

[@casual-goy8811]

How can you show us the collimation is perfect when you are only looking through one lens with your camera? 😁 mines need sorting out too. Thanks for the vid

[@knight2255]

Thanks, do you blokes have a wintertime? Do the birds chirp out like that 24/7/365?

[@robmurray2005]

Pretty much! They never shut up. Particularly in the morning and afternoon. we get magpies, cockatoos and kookaburras demanding food and dive bombing us when we eat on the deck. We have a winter for about 3 months, gets down to about 5c - about 40f but because we are on the coast it never gets too cold. Fireplace goes on about a dozen times a year. But even in winter the birds are always there

[@akshayaksis36]

so we got to loosen teh screw or adjust further after removing the grip ?

[@JasonBYU23]

You don't have to rip off the grip to get to the screws. Just lift the grip with a screwdriver or knife.

[@CatalunyaPortugal]

I have just bought from Amazon Spain a pair of Celestron SkyMaster 15x70 binoculars and, although I have no remark about the external conditions of the binoculars, which were perfect, I am not as sure about its optical performance. Terrestrial observations seem reasonable, but I bought them for astronomical observing and I see stars not as point light sources (as, for instance, with a pair of 10x50 binoculars that I also have), but as little globes with a small lateral light shadow, like little comets. I tried to focus but I couldn't achive a better image. Should I complain to the supplier and exchange it for binoculars in better conditions? Or that is the optical performance just expected for a model with an affordable price? José Ribeiro
