About this product
Turn faint guide stars into steady tracking points and bring deep-sky targets into view with the Sky-Watcher SynEye 662C. Engineered around a sensitive back-illuminated Sony colour sensor, this versatile imager excels at real-time autoguiding, fast pointing-model alignment, and Electronically Assisted Astronomy (EAA). Its compact profile and flexible connection options integrate seamlessly into guide scopes, off-axis guiders, and portable setups alike.

Precision Tracking and Fast Pointing
Achieving pinpoint stars during long-exposure astrophotography demands rock-solid tracking accuracy. The SynEye 662C features an integrated ST-4 style autoguiding port for direct, closed-loop corrections between the camera and your equatorial mount. Beyond keeping exposures sharp, the sensor's rapid frame rates make quick work of building sky models, refining your mount's GoTo pointing reliability across the entire celestial sphere.
Sensitive Low-Noise Imaging
Powered by Sony's back-illuminated STARVIS 2 technology, the 2.07-megapixel IMX662 colour sensor delivers exceptional quantum efficiency paired with remarkably low read noise. These characteristics make it ideal for gathering faint light during short exposures, allowing guide stars to register instantly even in star-poor regions. When paired with live-stacking software, faint nebulae and distant galaxies emerge on your monitor in vibrant colour far beyond what a traditional visual eyepiece can resolve.
Flexible Optical and Software Integration
Equipped with native M42 threads alongside a standard 31.8 mm (1.25") nosepiece, the camera adapts seamlessly to guidescopes, off-axis guiders, and standard focusers. A removable IR/UV-cut filter gives you the freedom to customise your optical train, while complete ASCOM compatibility guarantees smooth communication with third-party acquisition, planetarium, and guiding packages.
12-Bit RAW Data Depth Outputs pristine 12-bit uncompressed colour data, preserving fine dynamic range and subtle tonal gradients for cleaner live stacking and high-precision star centroid calculations.
