  • Starizona Variable M48 T-Threaded Adapter Kit

    The Starizona Variable M48 T-Threaded Adapter Kit provides a complete solution for achieving precise back focus, bundling three separate variable adapters into a single package. This kit covers a total spacing range from 15mm to 40mm using M48 threads. The three included adapters provide distinct adjustment ranges of 15-20mm, 20-30mm, and 30-40mm, allowing you to dial in the exact distance required by your imaging train components.

    A 3-Adapter Kit for M48 Spacing from 15mm to 40mm

    Achieving the correct distance between a focal reducer or field flattener and your camera sensor is critical for sharp, coma-free stars across the image frame. This kit from Starizona simplifies that process by providing three adapters that cover nearly any common back focus requirement from 15mm to 40mm. Instead of stacking multiple fixed-length spacers, you can use a single variable adapter to fine-tune the distance with high precision, eliminating sources of tilt and flex. This set includes adapters covering 15-20mm, 20-30mm, and 30-40mm, ensuring you have the right tool for different imaging setups.

  • What adapters are included in the Starizona Variable M48 Adapter Kit?

    The kit includes a set of three variable M48 adapters. Each one covers a different range:

    • 15mm to 20mm adapter
    • 20mm to 30mm adapter
    • 30mm to 40mm adapter

    What is the total adjustment range covered by the Starizona M48 Adapter Kit?

    The kit provides continuous adjustment across three ranges, covering a total spacing distance from 15mm to 40mm. The ranges do not overlap, with the first adapter covering 15-20mm, the second 20-30mm, and the third 30-40mm.

    How does the Starizona M48 Adapter Kit help when using a focal reducer that requires precise spacing?

    Most focal reducers and flatteners have a strict back focus tolerance, often within a millimeter. This Starizona M48 kit allows you to precisely set that distance without relying on a fixed stack of extension tubes. For example, if your reducer requires 25mm of spacing, you would use the 20-30mm adapter to dial in that exact distance for optimal optical correction.
