This is a trade-in in excellent condition.  The optics are clean; there is a small scratch on the bottom of the black tube that is purely cosmetic.  This includes the backpack, and all of the original equipment:  

  • 32 mm Plossl Eyepiece for 38x
  • 45° Erect Image Diagonal for terrestrial use
  • 8x21 Erect Image Finderscope

We have the box for this, so we can ship it to you.  


    The little C90 is a portable powerhouse telescope and spotting scope ideal for road trips. For those looking for a step up from the all-in-one Travel Scope and Adventure Scope packages, this is the scope for you.

    A great spotter scope for wildlife and mountain vistas, it also serves as a portable and capable night time telescope to observe the stars, nebula, and planets. The included image erect prism means the image you see in the scope is correctly oriented. For the best magnification, we recommend adding a Celestron 8-24mm zoom eyepiece, or X-Cel series eyepieces.

    Note: Does not include a tripod. We recommend the Regal Premium Tripod.
