What high-quality binocular will fit my 54mm IPD?

My interpupillary distance (IPD) is 54mm.  What high-end or medium-priced binoculars can accommodate that narrow an IPD? 

Thank you,

Deborah G.


Hi Deborah,

Here is a list of higher end binoculars that would accommodate your IPD needs:

A good deal of the mid-priced binoculars will have a more limited choice for IPD.  One of the few that works well for folks with a narrower IPD such as yourself, is the Celestron Granite.

If you have any other questions, feel free to email or call.

Best regards,

Questions about The Warbler Guide

How useful do you think The Warbler Guide will be for identifying birds in non-breeding plumage (juvenile and autumn)?

Thanks in advance for your help and time!

 Clay P.


Dear Clay,
Thanks for your inquiry about The WarblerGuide. 
This is by far the most comprehensive guide on warblers yet, and it is a treasure trove of information and photographs, as you might expect.  Each species has a dedicated description with primary photos; Distinctive Views and Additional Photos from various angles; Comparison Species, and Aging and Sexing. There are also detailed descriptions of each song.

 I really like the Quick Finder pages which help differentiate east fall, east spring, under view, 45 degree quick view, side quick finder, and face quick finder.  I could go on and on!  It's quite an amazing resource.

We sold out of the first shipment we received and now have more on our shelves here at the store.   

If we may be of further assistance, please call us here at Eagle Optics.

All the best,

Would like to digiscope with my Vortex Diamondback Scope


I have a wonderful spotting scope from you that I use for bird watching--a VortexDiamondback 20-60x80 Angled Spotting Scope. Is there a mount I could purchase that will enable me to take digital pix with this scope? I know nothing about digiscoping...need advice, please. I'm told not all cameras can be used for this.

Hi Lois,

Thanks for your inquiry. You have a few options for digiscoping with the Diamondback, but the set-up you need depends on the type of camera you’ll be using.

If you have a Canon or Nikon DSLR camera, you can use the Novagrade adapter system, which screws right into your camera body and tightens onto the scope eyepiece.

If you have a smartphone (which will take good-quality photos), you can use that with a Phone Skope Adapter for the type of phone you have. You would buy the fitted case for your model of phone, and then an adapter ring for the Diamondback:  Phone Skope C-3 Vortex Diamondback Optical Adapter.

If you have a point and shoot digital camera, it needs to have 3-4x optical zoom to work well for digiscoping. The adapter for using a point and shoot camera with the Diamondback scope is the Vortex Universal 28-45mm Small Digital Camera Adapter.  It’s a little clunky, will work well for your use.

Hope this helps, please let us know if you have any further questions!
