Astro-Physics 1.25" Adapter with Brass Locking Ring
The 1.25" adapter is included with Astro-Physics focusers (and refractors); however, they also offer it as an accessory to use with any telescope. It slips into a 2" opening and is used for 1.25" accessories. It features a brass locking ring and is threaded for 48mm filters. Please note that if you use long-barreled eyepieces, such as TeleVue Radians, you may strike the filter. In this case, we suggest that you add a 2" Barrel Extension w/ 48mm Threads to the bottom of the adapter before installing the filter.
