Bring Universal Compatibility to Your Telescope
A standard format for decades, the 1.25” barrel size for astronomy accessories is widely available and typically more affordable than the 2” options. This smaller diameter is prevalent amongst eyepieces and cameras designed for narrow fields of view, such as short focal length eyepieces and planetary cameras. Introducing use with these 1.25" accessories, this Apertura 2” to 1.25” Adapter helps you take full advantage of your telescope’s light gathering capabilities for a myriad of different applications!
Precision Craftsmanship
Offering a secure, rock-solid connection, this adapter is equipped with a brass compression ring. The uniform, even grip around your accessory not only provides better alignment with your telescope’s light path, but this design will not maim nor scratch your equipment. Crafted with CNC-machined black anodized aluminum, the Apertura 2” to 1.25” Adapter is built to last, withstanding repeated use. At the bottom of this adapter you’ll find threads to accept 2” (M48) filters.
