ZWO Off-Axis-Guider

ZWO Off-Axis-Guider allows both astrophotography and guiding with one telescope. Ideal for astrophotographers who want to combine sharpness and precision without an extra telescope. Thanks to its large prism (8×8 mm), it easily detects bright stars in the peripheral field, even at shorter focal lengths.

The optical body is extremely compact: with an effective length of only 16.5 mm, it fits perfectly into tight image chains, such as when using a filter wheel and cooled camera. The guider comes with a range of adapters (M48, T2, 1.25″) so you can effortlessly connect virtually any combination - from DSLR to ZWO ASI camera.

✓ Only 16.5 mm thick - fits virtually any optical pad
✓ Large prism (8×8 mm) - ideal for guidesterren at the edge
✓ Universal connection - M48, T2 and 1.25″ adapters included
✓ No more need for a separate guidescope - less weight and errors
