76mm Cassegrain Telescope


Congratulations! You have bought a wonderful telescope. This is a precision optical instrument, and you have many wonderful evenings of observing the night sky ahead of you. This on-line guide is to help you assemble your telescope properly.

Of course, the telescope comes with an assembly guide, and we were able to assemble our telescope less than 20 minutes using that guide. However, we know that many people are visually oriented and that pictures of the assembly process would be helpful. Since your telescope assembly guide and instruction manual does not have a lot of pictures, we have put together this online guide to help you assemble your telescope for your first night of observing. You can watch the video above and follow along with our picture filled guide below. Once your telescope is assembled and ready to go, the rest is up to you. Learning astronomy is all the fun anyhow! So let’s get started . . .

  • Necessary Parts for Assembly

    • 1x Telescope Tube
    • 1x Telescope Tripod
    • 2x Eyepieces (one is attached to the telescope)

  • Step 1
    Remove the tripod from the box, and extend the legs as shown in Figure 1 below.

    Figure 1 – Extending the tripod legs.
  • Step 2
    Unscrew the handle to loosen the up-down motion of the tripod. Set the tripod level and screw the handle in to tighten as shown in Figure 2.

  • Step 3
    Use the hand screw beneath the tripod’s mounting point to screw the telescope in to place. The viewing end of the tripod should be facing away from the handle.

  • Step 4
    If no light is viewable through the eyepiece, you may need to align the inner mirror. Simply twist the lens pictured in Figure 4 one full rotation, while viewing through the eyepiece. Stop once you see light.

  • Step 5
    To change eyepieces, simply unscrew the current one to remove it. Then screw in the other eyepiece until snug.

  • You’re done!
    Thanks again for your business. We hope you enjoy your new telescope!
