Alpine Astronomical T2-25C Overview

An optional part of their modular Astro T-2 system, the Alpine Astronomical Baader T-2 7.5mm Extension Tube can be used throughout the system to add the proper spacing between different components. The extension has internal T-2 threads on one end with external T-2 threads on the other for easy use. You can use the extension tubes anywhere you need to precisely space and couple any of the T-2 components, in configurations of your own design.

Example of Uses

  • Stack this 7.5mm tube with another of the same size or the two other sizes—15mm and 40mm—for precise spacing
  • Use with the Alpine telecompressor to vary the spacing of the lens relative to a camera or eyepiece for precise placement
  • Provide a secure way of varying an eyepiece-to-camera separation (projection ratio)
  • Use with the afocal and ocular projection (OPFA) system
  • Use with the Multi-Purpose Coma Corrector to accurately locate and couple the coma corrector to eyepieces
