This video helped me a lot. I had just asked the seller to give me another binos, but I knew they didn't have stock so wasn't happy about waiting for them to get a new shipment God knows when. So looked, catched this video, and tried it. With a precision screwdriver, collimated just the left tube, quarter of a clockwise turn on the outside-up screw, quarter of a anticlockwise turn on the inside screw, as I have heard those are complimentary and if you screw both on the same direction, the prism housing could be set loose, or the prism could be broken or nicked. It had before vertical miscollimation, the left tube was pointing a little upward with respect to the left tube. So those movements pointed the prism downward perfectly for what I needed, getting in line with the right tube. Cancelled the request, I'm keeping these binoculars and they are perfect now, checked on the night sky with open clusters. Want to add that what one does with this tweeking, is called "conditional collimation" and it works on the set interpupillary distance you had when adjusting. Therefore, it could show miscollimation with another person whose eyes are more widely or closely separated than you. But anyway, it's so easy to adjust, and I feel much confident with it by fixing it now, that it's an interesting alternative to weigh in, instead of waiting for another set that could also be miscollimated (the problem is quality control and rough shipping, I bet the Pro version hasn't this problem on this high level).
I appreciate the video. I tried collimating these and it made little difference. The only way they function properly is by "closing" each side so the eyepieces are as close as possible to each other, which alleviates the collimation to an extent, but makes using them comfortably far more difficult.
It sounds like they are a good product when they are aligned correctly. Ive seen a few videos now that talk about Celestron and the colimation issues . Its good that they are easy to fix . Some compact binoculars are sealed up and dont seem to have any way of resetting colimaton as the case is hard and has no way of prising it off to get at the lenses or prisms
Got as a gift last week. There really gd I'm west of Scotland sky's are clear just now Think I seen Venus lastnight sky was full of stars Oris s belt been clear for wks Would recommend. The cover for eye lens a bit flimbsey but Other than that impressed 💪
I have just ordered this Clestrone Skymaster 15×70 after watching all reviews. I believe this is good for sky watching and terrestrial view as well. I have no idea if incase collimation thing happens. Help me for this. Thank you for the video.
merhaba yeni bir çift aldım 25x70 bazen çift görüyorum istediğim birleşmeyi alamıyorum gibi emin değilim ama bu coalimasyon sorunumudur bazen çift görüyorum mesela çatıda 3 adet baca var ben 4 adet görüyorum gibi sizce bu nedir kafam karıştı
Hello! I received my skymaster 15x70 binos 3 days ago. I dont see double image with it, but after using it for a while i have dry eyes and a little eyestrain. Can it be the same problem, that its out of collimation and how can i check it? Thanks for the answer!
I have a celestron 15-35x70 I want to clean it inside but iam not opening the barrel it's fixed some kind of gum please help me to open this binacular or I am not happy for this binacular it's my fast costly binacular but lens quality is good but service is big problem this binacular
I just bought a pair of those. Great binoculars I will never sell them. Not as impressed with my 25 x 70. More difficult to focus. And the views were not any better. My 15 x 70 were in perfect collimation. Not sure about the 25 x 70.
Good to know, but if they came like that take them back to the store and have them collimate them for you. When you buy a binocular it should be ready to use.
@@robmayor8922 Since when? I have several pairs of binoculars from small to giant that I have used over the years. I never had any problems, and I never heard of anyone in my astronomy groups have issues with this. Always try them out before you leave the store and stay away from cheap binoculars.
@@julianparks8485 if they are being shipped, then you aren't able to try them in the store are you? It's quite easy for them to be knocked out. You say 'stay away from cheap binoculars' but not everybody has the luxury of being able to buy expensive gear and so go for the best they can afford to enjoy their hobby. This is a simple way to correct the collimation which for many may be preferable to going through a return shipping process.
As an aside I think the 'avoid all cheap gear' mentality in astronomy is really unfortunate. We would all love to have the most expensive kit but it's not possible and this way of thinking excludes many from the hobby as they don't think they can enjoy it without spening £££££. Is it really worth it for someone with a passing interest to spend hundreds on a pair of binos they may only use a few times a year?
@@robmayor8922 I've ordered several pairs of binoculars and had them shipped to me. None were defective. If they had been, the seller gave you time to try them and return them if they were defective or not what you wanted.
