  • Starizona M48 Extension - 10mm

    The Starizona M48 Extension tube adds a precise 10mm of length to any optical train using standard M48 threads. This simple, rigid component features both male and female M48 threads, allowing you to insert it between flatteners, reducers, off-axis guiders, and cameras to achieve the exact back focus required by your optics.

    Achieving 10mm of Critical Back Focus

    Every field flattener or reducer has a specific back focus distance—the exact spacing required between the corrector and the camera sensor for sharp, round stars across the entire field. This Starizona M48 extension provides a fixed 10mm of spacing, helping you bridge the gap when your existing adapters don't add up correctly. It is an essential tool for fine-tuning your imaging setup and eliminating elongated stars at the edge of your frame caused by incorrect spacing.

  • What are the threads on the Starizona 10mm Extension?

    The extension uses standard M48 threads. It has male threads on one side and female threads on the other, allowing it to be inserted anywhere in a typical M48-threaded imaging train.

    When would I use the Starizona M48 10mm Extension?

    You would use this 10mm extension when the total distance from your corrector lens to your camera sensor is not correct. For example, if your flattener requires 55mm of back focus but your current adapters only provide 45mm, adding this 10mm extension will achieve the required spacing.
