The SV198 50mm aperture guide scope with a built-in dual helical focuser is known for its versatility, let alone the lightweight. Together, all of those make SV198 a perfect tool for guiding, searching, and spotting. The full multi-coated achromat glass brings excellent optical performance, makes it great for both sharpness and color. BTW, it also could be used as a right-angle correct-image optical finder scope (Eyepieces and Prism Diagonal sold separately).

  • SV198 50mm f/4.1 mini Guide Scope
  • Two-Ring bracket with a dovetail
  • 6PCS Nylon-tipped thumbscrews
