Gosky Telescope Phone Adapter Quick Aligned Cell Phone Digiscoping Adaptor Mount - Compatible with Spotting Scope Binoculars Monocular, Fit Almost All Brands of Smartphones (Big Type)

No issues, stout durable tough plastic, adjusting knobs seem to work ok, easily adjusts. Fits my iPhone XS with or with out the Otter box traction case. Plenty adjustment, does not interfere with phone buttons, etc.. Eye piece fits Swarovski STS 20 x 60 x 80mm spotting scope. Also fits Zeiss FL STR 20 x 60 x 85mm Spotting scope, no problem, plenty adjustment. It seem to fit my Vortex Viper 10 x 42 and Leica Geovid 10 x 42 binoculars as well but is really close to the end of the adjustment. Probably won't work with med to small bino eye pieces, you should get the smaller Gosky adapter if so. Some reviews stated its to bulky, Its not that bad for what it fits! I also have the Nova Grade adapter. It works great as well, Excellent built, excellent material, all very precisely machined high grade,, but "very expensive" compared to the Groski. I would not have bought the Nova Grade if I had bought the Goski first! It works just fine at 35 bucks!!

I bought this mount awhile back. Should of checked it out before tossing it in my bag to be used when needed. Now that I need it, I found it will not mount properly to my scope/binoculars. The mounting plates are not even. One of them is set futher back than the other two so when I tighten it down, the center viewing hole is not aligned with the binoculars. Seems like it would be a good product. Just make sure to check that it's put together correctly when they arrive.

I bought one for my Vortex Razor HD spotting scope. It works well (not as quick and exact as phone skope) and takes a few tries at dialing it in. It's less than half the price of phone skope and you won't have to buy a new piece to fit your new phone. This is VERY adjustable, and fits anything from binoculars to spotting scopes with large eye pieces (it also fits smaller eye piece spotting scopes). I liked mine so much that I bought one for my buddy. He loves it and was able to video my entire hunt from nearly a mile away through his spotting scope (leica). I would recommend it because they are so adjustable, priced fair, and pretty will made. I am getting ready to buy a different phone without worrying if it will fit it. It will.

After reading all the negative reviews I was a bit skeptical about purchasing this phone adapter. I am using it with an iPhone on a Vortex Spotting Scope. I have used the PhoneSkope in the past but they don't have one to fit the current iPhone. I bought the Gosky to replace that in hopes that it would work. The Gosky Adapter is by far the best I have used. It was easy to set up to the Vortex scope and easy to install the iphone even with the case on the phone. If anyone is trying to add a camera to their spotting scope I highly recommend this Gosky Phone Adapter. Fits well and holds tightly to the eye piece. The only minor problem that I have had is with the felt liner rolling up if I don't loosen the locking screw enough when removing the phone. I now know how to solve that problem as well. The attached photo is an example of the Gosky Adapter in use on the Vortex scope with an iPhone.

I purchased this to replace a flimsy one that came with a scope that I purchased. The first two times that I used it, it worked beautifully. Since then, it is now in possible to make adjustments so that light does not leak in around the lens. If you are serious about scope photography, I would recommend that you purchase something more professional. I thought that spending this amount of money would solve my problem. It did not.

I like it only because it can fit up to 68mm diameter , but it needs to be deep cupped enough to grapple the nearest vertical side of tapered tops of large eyepieces.. It can only go deep as 25mm from the top which means only part of the three pronged pincers make contact with very little of the vertical side . it just slips out too easily . I think the cup need to be deeper at least 15mm more or a total of 40mm to be workable for most of large 2" eyepieces or wide 1.25 eyepiece types. it probably works with cheap Plossi types that do not have tapered tops. Cheap Plossi types have narrow FOVs .

REVIEW UPDATE After writing my review, Gosky customer service emailed me offering to send me a replacement. While trying to attach it to my binoculars, the gripper misalignment occurred again. It was suggested that I was trying to over tighten it and they sent me another replacement. Now I realize they were right - the adapter only needs to be snug when using with binoculars. For a scope, it needs to be somewhat tighter to keep the weight of the phone from causing it to rotate. This works well with my Kowa TSN 883 scope. It’s still a little tricky to keep it aligned when attaching to the scope but I think it will just take some practice So, I am revising my review. The adapter works well and Gosky’s customer service is great. ORIGINAL REVIEW It seemed to be exactly what I was looking for. The adjustment to line up my iPhone 12 was easy enough but it was very difficult to keep it in position when attaching it to my scope. Then I noticed I had the problem of one of the grippers in the wrong position as several other reviews have mentioned which misaligned the exit pupil of the scope eyepiece with the aperture in the adapter. I will return it and search for something sturdier.

NOTE: the dark circle around the moon and cormorant is called vignette and I put that there after shooting the photo! I bought this because for $25 how can you argue. It fits the eyepiece in my Vortex Razor HD which has an OD of 5.5cm. It’s got a twist to tighten mechanism and locks right down, centered on the eyepiece. I previously had the Gosky model with the clamp you need to tighten. The metal bars were so narrow they left impressions on my eye relief cup. I didn’t like this at all. The large round coupling on this tightens all 360* around the eyecup, avoiding any pressure spots. Also it’s plastic so it won’t damage your eyecup as easily. The phone locks well into position via the tightening screw on the swing arm. The adapter tightens nicely to my phone as well. I have numerous issues with the Phoneskope platform. First: it’s like $80 which is a wicked turn off. I wouldn’t mind spending that if it was a one time thing but the fact I need to keep buying new cases for new phones and new couplings for new scopes and a separate coupling for my binos, at the end of the day the Phoneskope comes with a need to continually upgrade and update your hardware. This Gosky is universal. I can use my phone, I can use my girlfriends phone when we go birding. I can use the next phone I buy, and the one after that! It’s universality is really a HUGE selling point.
