The 2″ extension tube is an ideal problem solver if the focal plane is too far outside. The focuser remains in its optimal position.

Fields of use:

  • straight-through observation with refractors (normally, the standard focusers are not long enough for that)
  • observation with photo-optimized Newtonians having a longer back focus distance

Technical details:

  • precisely CNC machined
  • made of aluminum
  • brass compression ring prevents your accessories from dents and scratches
  • with filter thread at the telescope side
  • Optical lengths available:
    • 35mm.
    • 50mm.
    • 80mm.
