⚠️ Adapters are sold in pairs.

Add more eyepiece adapters for any Analog Sky binocular with 2” focusers. Our adapters all provide click-lock tabs for quick, secure insertion into Analog Sky focusers. These tabs are generally not compatible with standard 2” telescope focusers but can be removed easily with a hobby blade.

Adapters come in standard, -10mm, and +10mm depths to create more in-focus and out-focus.

They also come in a variety of styles you can select below:

Standard w/screws: Grub screws semi-permanently attach this adapter to your 1.25” eyepiece and defeat any undercut. They also allow you to tweak collimation of eyepieces. (2mm hex wrench required)

Standard w/upgrade nylon-tipped screws: Same adapter with high-quality non-marring nylon-tipped grub screws. Select these screws as an add-on product next to the “Add to Cart” button.

Gripfin Loose: Adapters with gripfins don’t require screws. Eyepieces just slide in and the flexible fins hold them securely and perfectly centered. The loose gripfins balance grip and ease of eyepiece insertion, allowing you to easily share your binocular eyepieces with other telescopes in the field.

⚠️ All Analog Sky printed parts are made-to-order to ensure you receive the most up-to-date versions. They may take a week to print, QC, and ship.
