Imaging Adapters

Connect a DSLR, mirrorless, or astro camera to your telescope for prime-focus and projection imaging.
Everything for the camera side of the optical train — prime-focus adapters, T-rings and T-adapters, eyepiece-projection couplers, camera-bayonet barrels, and extension tubes for setting imaging back-focus. Observing by eye instead? See our Visual Adapters.
To image through a telescope, your camera has to reach focus at the right distance and lock solidly to the focuser. These adapters handle both jobs. Prime-focus adapters turn the telescope into the camera lens for the widest, brightest field. T-rings and T-adapters bridge the universal T-thread (T2 / M42×0.75) to your specific camera bayonet and to the 1.25" or 2" focuser. Eyepiece-projection couplers place an eyepiece in the light path for higher-power lunar and planetary work, and extension tubes let you dial in the exact back-focus your camera and corrector need.
Astrophotography hardware lives or dies on fit. Listings call out the three astronomy barrel standards — 1.25", 2", and the legacy 0.965" — along with the T-thread (T2 / M42×0.75) and SCT thread (2" × 24 TPI) wherever they apply, so you can match parts with confidence before you buy.
It connects your camera body directly to the telescope so the telescope itself acts as the lens — no eyepiece in the path. This gives the widest field and the brightest image, and it’s the usual starting point for deep-sky imaging. You’ll typically pair it with a T-ring matched to your camera’s bayonet.
A T-ring adapts the universal T-thread (T2 / M42×0.75) to your specific camera mount (Canon EF/RF, Nikon F/Z, Sony E, and so on). A T-adapter carries that T-thread to the telescope side — a nosepiece that drops into a 1.25" or 2" focuser, or a thread that mates to an SCT or focuser. Most prime-focus setups use a T-ring plus a T-adapter or prime-focus adapter together.
Prime focus uses no eyepiece and gives a wide, bright field — ideal for deep-sky targets. Eyepiece projection puts an eyepiece between the telescope and camera to magnify the image, which suits high-power lunar and planetary imaging at the cost of a narrower, dimmer field.
Match three things: your camera’s lens mount (for the T-ring), your focuser or rear-cell thread (1.25", 2", SCT 2"×24 TPI, or a focuser thread), and the back-focus your imaging train needs. Each product page names the relevant standards. If you’re unsure, email support@cxbastro.com with your scope and camera and we’ll help you confirm.
Pair these adapters with off-axis guiders, focus masks, and the visual side of your kit.
