Spacer Rings, Extenders, and Telescope Adapters

Spacer rings, extension tubes, and adapters for telescopes are essential imaging accessories for achieving precise back focus and a perfect fit between your optical instruments. These devices compensate for variations in distance between the telescope and cameras or accessories, ensuring optimal focus for astrophotography and visual observation.

Available in a wide range of formats and sizes, these rings and adapters are compatible with most telescopes and DSLR, mirrorless, or CCD cameras. Extenders and spacer rings also allow you to adjust the sensor position to achieve the best focal plane, a critical factor for capturing sharp, detailed images of celestial objects. To complete your setup, explore our full range of adapters, extension tubes, and spacers, including T-rings, T-mounts, T-adapters, and much more.

At Astronomy Plus, we offer a carefully curated selection of reliable and easy-to-install extension tubes, spacers, and adapters for telescopes. Choosing the right accessory ensures a precise fit for your equipment, preserves the integrity of your instruments, and optimizes your astrophotography sessions, whether you’re a beginner or an experienced observer, allowing you to fully harness your telescope’s potential.
