On Glass Adapter Ring + MagTab

The Adapter Ring and MagTab are the phone half of the On Glass digiscoping system. The ring sits on your optic's eyepiece and holds the magnets. The MagTab sticks to your phone case, and the two snap together with the camera lined up, every time.

It works with any phone and any case. Made in the USA.

• Adapter Ring: takes any of the eight On Glass spacers
• MagTab: low-profile magnetic plate, fixed to your phone case with 3M adhesive

The ring needs an Optic Spacer in the size that matches your eyepiece. The simplest way to get both is the On Glass Adapter Kit.
