  • Starizona Variable M42 (T2) T-Threaded Adapter 30-40mm

    The Starizona Variable M42 (T2) T-Threaded Adapter provides precise, adjustable spacing from 30mm to 40mm for any optical train using standard M42 T-threads. This single component replaces a collection of fixed-length spacers, allowing you to dial in the exact back focus required by your camera and corrector combination within its adjustment range.

    Fine-Tuning Back Focus from 30mm to 40mm

    Achieving the correct back focus is critical for sharp stars corner-to-corner, especially with field flatteners and coma correctors. The Starizona Variable T-Threaded Adapter simplifies this process by offering a continuous adjustment range from 30mm to 40mm. Instead of swapping out multiple fixed spacers, you can simply rotate the adapter to lengthen or shorten the optical path, letting you find the perfect spacing with sub-millimeter precision. This is essential for optimizing imaging systems where the exact distance between the corrector and sensor is non-negotiable.
