Deluxe Off Axis Guider For Astrophotography With Fixed Orientation Helical Focuser For Pro Grade Auto Guiding And Top Notch Light Transmission 12 5mm Prism For Maximum Clarity And Ultra Accurate Star Tracking
✔️ 12.5 mm prism with fixed-orientation helical focuser and adapters
The Off-Axis Guider is an essential astroimaging accessory built for long focal length telescopes. It uses a 12.5 mm prism to intercept a portion of the focal plane for guiding, delivering precise star tracking. This single-unit kit includes spacers and adapters for DSLR cameras, Nightscape CCD cameras, and other popular imaging setups, compatible with Schmidt-Cassegrain and EdgeHD systems.

💡 What is an off-axis guider used for in astrophotography?
An off-axis guider helps you capture sharp stars by guiding on a separate sensor from the main image sensor, reducing tracking errors and flexure in long exposures.
- Improves guiding accuracy on long exposures by tracking a guide star near the edge of the field
- Includes adapters and spacers for DSLR and Nightscape CCD cameras for easy setup
- Helps reduce optical flexure and alignment drift for pinpoint round stars
