Telescope Assembly

Telescope “specs”

  • It weighs about 520  pounds (236 kg) fully assembled
  • At its maximum height, it about 9 ft (2.75 m)
  • The OTA is about 6.5 ft long (1.98 m)
  • The heaviest individual part, the polar axis, weighs about 100 lbs (45 kg)
    • Admittedly, this requires some brute strength to get into place (I use lifting straps to make it a relatively easy step)

Despite my telescope’s size, I can set it up by myself in about 1 hour  Take apart is about the same

I designed the components with a poka-yoke assembly in mind.  This approach allows the parts to be assembled easily.  It also ensures pretty good repeatability of the assembly making things like mechanical and optical alignments quick

It is capable of being a great visual scope as well as amazing photographic instrument

Some Design and Other Details

When I started to design the 18 inch f/4.5 telescope, I considered several designs.  I looked a horseshoe mount, a German Equatorial Mount (GEM) with the worm gear at the of the polar shaft adjacent to the declination axis.  Ultimately, I chose an “old school” design with the worm gear at the bottom end of the polar shaft.  This approach improved the center of gravity (CG) to be closer to equatorial head.  It also allows for easier access to the worm gear.

Design Considerations

Coming Soon

Yep, coming soon too
