SBIG Star Chaser SC-2 Off Axis Guider

By using the same optical path as your main imaging camera, the SC-2 completely eliminates differential flexure. This ensures your guide stars and imaging target stay perfectly aligned, which is critical for long-exposure shots where even tiny shifts can blur your images.

The unit is designed with a very thin 20.3 mm profile, which is intended to minimize back-focus consumption. However, you should always verify your total back-focus requirements to ensure it fits comfortably between your camera and telescope.

The mechanical shutter allows you to take dark frames without needing to cover your telescope aperture. This makes the process of calibrating out sensor noise much faster and more convenient during your imaging session.

Yes, it is specifically designed to support Adaptive Optics technology, such as the SBIG AO-8A. This combination allows the system to actively correct for mount tracking errors and atmospheric seeing conditions in real-time for sharper results.

Yes, the pick-off mirror position is adjustable, allowing you to optimize the field of view to find a suitable guide star. Focus is also easily managed with a simple knob, making it straightforward to dial in sharp stars.

The sensor features 4.8-micron pixels and high sensitivity, which is well-suited for capturing faint guide stars. The global shutter design also ensures that your guide images are free from the rolling shutter artifacts that can sometimes complicate tracking.
