Question: How can I get it to fit Celestron Skymaster 15x70 without the black circle on the screen using my iPhone 5?
Document: Works exactly as described with my iPhone 5 and Celestron 15x70 Skymaster binoculars. It takes a bit of practice to use correctly, but there are helpful tips on the manufacturer's website.
Make sure to put it in video mode on your iphone.. the picture stabilizes better than photo mode. Plus you can capture your shots!It came with two different rubber rings and an adapter for older iphones. The instructions were.... ok. But it's simple enough to figure out without even looking at them.I may try a little rubber cement on the ring to see if I can get a tighter fit.Bottom line:Is it going to be perfect for everyone... no.
I am glad I did not by the 100 dollar version of this thing. It will not fit Leupold Arcadia 10x42 binoculars. It will fit my cheaper Simmons 10x42 as long as you fold back the rubber eye piece and it doesn't stay on that well as I read in other reviews but had to give it a try. It also looks like you are looking down a tunnel. The entire screen is not visible just a round circle.
I bought this to use with my pair of Nikon action 16 x 50 and my Reddfield 8 x 42 binoculars and so far it works great. When attaching the hook up to my Nikons I had to take the rubber ring that goes around Black plastic piece that attaches to the binoculars in order to get it to fit. They fit perfectly with the rubber adapter removed and I am able to take high-quality pictures from over 200 feet away.
Used this on spotting scope, results were nothing less than amazing. No more eye strain, it's even easier to adjust scope using the iPhone screen. Can record and playback shots. But be warned. Camera drains iPhone battery very quickly.
This was a great idea which I hope to visualize when I connect to 5 iPhone. The concept is great so Im looking forward to using it. I will verify and hopefully adjust my recommendation with praise for great pictures.
I just received the Carson HookUpz and it works just fine with a Nikon ED50 scope with the eye cup folded down. It is not too tight so I will need to hold the Iphone 5 as well as stead the scope but this is all necessary to get the scope stead to take a picture. The Nikon has a 15-30 x zoom and that is fine for most scope views.
This &#34;Carson Hookupz&#34; indicated that it works for iPhone 4/4S. It is for the iPhone 5/5S as indicated on the packaging. There is a little add on sticker that says it works for 4/4S, but it does not. The camera eye does not get to the center of the peep hole. Which means that you can never see through the scope the way it was meant to be done. I will be returning this item.
Trying to focus binoculars, hold my iPhone to the eyecup and use the camera button proved to me I needed help. Then I saw these on Amazon and decided to try them despite some negative reviews. I found by using the correct adapter, making sure you're  really steady(use a tripod) they perform just as advertised. I tried them on my 10x42 binocs and got beautiful results. I don't know why  others had such bad results, But they worked for me!! 5 stars.
not a lot more to say, they work perfectly with my Zeiss Conquest 10x30 BT and iPhone 5.I was expecting that the fit might no be perfect or that I would have to shim this or that.This centers the camera perfectly and I can see and record far away with my iPhone 5.
Answer: Not sure if it will work for you but I have the same thing. I just zoom the phone only enough to get rid of. Of course you can zoom further if you like, I do that all the time
