    It is quite difficult to find a Klevtsov or Rutten design unless you find a smaller optical house that specializes.
    Skywatcher has not released anymore information on the Rutten that they were showing at various EU astro shows.

    Refractors kick arse precisely because they don't hide behind excuses. That is, they have no obstructions to hide behind.

    It’s a shame. The Rutten design is the next best thing to an apo.
