Product description

  • Extension tubes allow you to reach the perfect distance of focal point for photographic use.

In astrophotography, the working distance has a major influence on the quality of the image. Precise adjustment is therefore important. This "Backfocus Adjuster" makes this much easier.

With an average length of 18 mm, the working distance can be adjusted by ± 2 mm.

The adaptor is CNC-milled and has a 0.05 mm precision adjustment. The printed scale makes it easy to use.
