Digiscoping adapter questions for my Vortex Razor scope

I purchased the Vortex Razor HD 16-48x65 Angled Spotting Scope last year. I am interested in purchasing an attachment for my  to allow me to digiscope with it. 

On your web site it appeared that you had an adapter that was suitable for this camera.  I wanted to check with you before I ordered the adapter. 

Also, I have also read  that there is a digiscoping adapter for iPhones.  I have iPhone 6 -- do you sell these adapters?  Do you know that they can provide good pictures?




Dear Jeri,
Thanks so much for your inquiry.

For digiscoping, a point-and-shoot camera needs to have an optical zoom of 4x or less. While I'm not familiar with your Canon Powershot, I looked its specs up online, and it has an optical zoom of 30x. While it might be a fine camera, it will not work for digiscoping, unfortunately.

The iPhone 6 will take amazing photos! It is great for digiscoping. You have two choices for iPhone 6 adapters that I am aware of. First is the Kowa TSN IP6 iPhone 6 Digiscoping Bracket which will fit your Razor.  The second is to go to Phoneskope also makes an iPhone 6 adapter that will fit the Razor scope.

If you have any other questions, please don't hesitate to ask.

All the best,

What differences will I see in a 8x42 and an 8x50 binocular?

If I'm considering a 8x42 binocular and an 8x50, what differences would I be seeing between the two sizes in terms of optical quality?


Jim K.


Hi Jim,

Thank you for writing and for your interest in Eagle Optics!

Imagine you have two binoculars with the exact same glass quality and optical coatings, but one is an 8x42 and the other is an 8x50. Let’s say your pupillary opening just happens to be 3.5 mm in the particular lighting situation you’re in. As such, you will not be utilizing the full exit pupil of either binocular (5.25 mm & 6.25 mm respectively). 

At first it might seem that there would be no difference in image quality between these two binoculars, but that would be an error. Not only does aperture increase brightness (when your pupillary opening can receive it), but it also improves resolution regardless of pupillary diameter. Thus, the 8x50 in this example will render slightly more detail because the 3.5mm exit pupil you are taking into your eye is comprised of more photons of light: resolution is a function of aperture size.

Please let me know if there is anything else I can do for you.

How much will a repair cost for my EO Ranger?

I have Eagle Optics Ranger Platinum Class 8x42. I need to have them repaired. I accidentally left the binocular on top of car an drove off. Both eye cups were broken off. I can not adjust, but the lenses still work great. Any idea how much to have them fixed?

Questions about the Kowa TSN IP4S iPhone 4/4S Digiscoping Bracket


So is this only the frame or it will come with the scope ring too?




Dear Miran,
Thanks for your inquiry.

The Kowa TSN IP4S iPhone 4/4S Digiscoping Bracket comes with the bracket and two rings. One ring is larger to fit a scope eyepiece and the smaller one fits some binoculars. 

Under the description on the website, it gives the measurements of each of the rings. If you click on the “Media” tab on the product page, you’ll see a short video which shows the product, how it works, and what is included. You can view the video here:

If you need help figuring out if it will fit your scope's eyepiece, just give us a call.

All the best,

Which binocular for my 8-year-old birder?

Good Evening,
My daughter has recently become a member of Illinois Young Birders and went on her first field trip a few weeks ago.  She was  lucky enough to be able to use the group's Eagle Optics binoculars, and we're interested in purchasing a pair of our own, as my daughter really needs to practice how to use them.  

She struggles with locating the birds with binoculars, so I want to work with her, as I know they are so valuable when birding and will make her experiences so much better.
Can you recommend which type of your line would be best for her?  Again, she's 8 and has a difficult time seeing a bird in the field then locating it with a binocular, as well as focusing.

Thank you!
Christine T.


Hi Christine,
Thanks so much for your inquiry.

For a young person, the most important things to look for in a binocular are low magnification (for wide field of view and ease of steadiness), and a lightweight profile.

The Eagle Optics Kingbird 6.5x32 Binocular fits the bill quite nicely.  Its porro prism design also enables the eyepieces to come closer together for smaller faces. Another must.

We sell many of this model to youth groups and education situations where young people are involved. It’s a great choice—and has an unconditional, lifetime warranty.

Though the Kingbird also comes in an 8.5x magnification, the 6.5x is best for younger people like your daughter, because it has a wider field of view (easier to find birds in the field) and it is easier to hold steady. I wouldn’t do the 8.5 for her age and ability.

If we may be of further assistance, don’t hesitate to call the store at 800-289-1132.

All the best,

Eagle Optics
