Review on Serounder Extension Telescope Astronomical Telescopes by Brandon Grzankowski

Revainrating 1 out of 5

The 2 inch section is uneven in diameter. very sloppy fit

The diameter of this 2" section varies from 1.99" at the end to 1.94" at the end. Set screws are available. Because the diameter differs by 0.060 inch, when tightening the set screws to the same size, the adapter twists and the optical circuit no longer follows the optical axis.

Pros
  • The front end has a 0.75 thread that can be used to carry the filter.
Cons
  • Negative Present
