    All Tele Vue Telescopes sold since 2012 come standard with a Feather Touch pinion assembly.  The Feather Touch  pinion assembly for Tele Vue does not look like a standard Feather Touch because as we machine the knobs to Tele Vue's specifications but all the inner workings are the same exact parts that comes with a 2" Feather Touch Crayford focuser.

    Below is the information if you want to upgrade your telescope with a Feather Touch pinion assembly.

  • Fastar Compatible Celestron Telescopes

    The Fastar system in combination with the Starizona Hyperstar dramatically increases traditional Schmidt Cassegrain and EdgeHD optical tubes' speed, turning f/10 instruments into f/2 or better.  The Fastar system provides greatly reduced exposure times for astrophotographers, increasing the ability to use larger imaging sensors, and eliminating the need for secondary wide-field telescopes.

    Celestron optical tubes will have a Fastar logo on the secondary mirror cover, indicating that the mirror can be removed and replaced with a Fastar lens or Starizona Hyperstar.
