Askar 107PHQ User manual

  • Hello! I've read the user manual for the Askar 0.7x reducer, designed for use with 107PHQ and 130PHQ telescopes. This reducer features a triplet design with ED glass and a standard 55mm backfocus. It also comes with M68, M54, and M48 adapters and will shorten the focal length to 524mm. I'm ready to answer any questions you have about its features or usage.
  • What telescopes is this reducer compatible with?
    What is the focal reduction factor?
    What is the backfocus of the reducer?
    What thread adapters are included?
