Atik T2 adapter for Atik One Kit (adaptations without Off Axis Guider)
... mounts to the Atik One instead of the Off Axis Guider
The Atik One kit comes with directly attached Off Axis Guider. For use without guider, (for example, with telephoto lenses), you need this T2 adapter. Back focus from the T-thread to the sensor is 28 mm (filters not taken into account).
