Kasai linear binoviewer review Contrary to other binos, with the Kasai linear binoviewer no path corrector or Barlow lens is necessary to get into focus. The device has been sold for some years now under different brand names like Orion, Omegon, TS and Auriga. In our opinion the linear binoviewer is a valuable and well-designed tool, not for high-power planetary observations, but for low- and medium-power widefield stargazing with Newtonians and refractors. We gave it a closer look, read our review.
