Kowa Digiscoping Adapter
We fit the full Kowa Prominar TSN range, from the compact 500 series through the 553/554 and 663/664 to the 55, 66, 77, 88 and 99. The TSN-88 and TSN-99 are favorites with birders and long-range shooters who want the best image a phone can pull through glass. Pick your model above and the right eyepiece is already selected. The Mountain Mag is a magnetic digiscoping adapter: the eyepiece stays on the Kowa and the phone snaps on whenever you want to digiscope. The phone half is the Mountain Mag Adapter, sized for your exact iPhone, Samsung Galaxy or Google Pixel.
WHICH KOWA DO I HAVE?
Kowa prints the model number on the scope body and the box: TSN-883, TSN-554, TSN-501 and so on. Find it and pick the matching TSN entry in the dropdown above; angled and straight versions of the same scope are listed together. If you run an eyepiece that did not come with your scope, email us the eyepiece model before you order and we will confirm the right pick.
