Is there an iPhone bracket that will work with my Kowa TSN 824?

Hello Eagle Optics,

I am trying to figure out if the Kowa TSN IP5 iPhone 5/5S Digiscoping Bracket is compatible with the 20-60x zoom on a TSN-824.  The text says it is compatible with the 77/88mm zooms, but I know both of those are physically larger than my old 82mm, so I'm kind of assuming it is not.  If this adapter is not compatible, is there one that is? 

Thanks for your help,

Hi Aaron,
Thanks for your inquiry. You would need to measure the diameter of your eyepiece. As stated on the description of the Kowa TSN IP5 iPhone 5/5S Digiscoping Bracket, the scope adapter ring measures 56 millimeters.

If your scope’s eyepiece has a fold-down eyecup, you will want to measure to accommodate it. I’m not sure if the bracket will work with that type of eyecup or not—you’d just have to try.  You can always return the bracket if it doesn’t work for you.

Phone Skope ( is a company which makes brackets for various smart phones and can also make custom rings to fit specific scope eyepieces.  That would be your best bet if the Kowa bracket doesn’t work.

Kind regards,

Eagle Optics

  1. Hi,
    PhoneSkope adapter C-3-011-A for Vortex Diamondback 60mm is the one we have fitted to several Kowa 820 series 20-60x zooms here in the UK (with rubber eyecup folded down).
    Hope this helps,
