  • Starizona Variable M42 (T2) T-Threaded Adapter 15-20mm

    The Starizona Variable M42 (T2) T-Threaded Adapter provides a precise, adjustable length from 15mm to 20mm, essential for achieving exact back focus in an imaging train. This adapter uses the universal M42 T-thread standard, allowing it to connect cameras, filter wheels, and correctors that require fine spacing adjustments within its 5mm of travel.

    Precision Spacing Control from 15mm to 20mm

    Achieving the correct distance between a field flattener or reducer and the camera sensor is critical for sharp, coma-free stars across the entire image. This variable adapter simplifies the process, replacing a collection of fixed-length spacers with a single, adjustable unit. By twisting the adapter, you can dial in any length between 15mm and 20mm, then lock it securely in place. This allows you to fine-tune your spacing to match the exact requirements of your optical system. For different spacing needs, Starizona also offers 20-30mm and 30-40mm versions.

  • What is the adjustment range of the Starizona Variable T-Threaded Adapter?

    This specific model of the Starizona Variable Adapter allows for a continuous adjustment of its length from 15mm to 20mm.

    What threads does the Starizona 15-20mm Variable Adapter use?

    The adapter uses standard male and female M42 (T2) T-threads, making it compatible with a wide range of astronomy cameras, filter wheels, off-axis guiders, and other T-threaded accessories.

    Are other adjustment ranges available for the Starizona Variable M42 Adapter?

    Yes. In addition to this 15-20mm version, Starizona also offers adapters with adjustment ranges of 20-30mm and 30-40mm to cover a wider variety of back focus requirements.
