Understanding the 130mm Telescope

What is a 130mm Telescope?

A 130mm telescope refers to the diameter of its primary lens or mirror. This measurement determines the telescope’s light-gathering capability, with a larger aperture allowing for more light to enter the instrument. The 130mm telescope offers a good balance between size and portability, making it a popular choice among amateur astronomers.

Key Features of a 130mm Telescope

  • Aperture: 130mm (5.1 inches)
  • Focal Length: Varies depending on the model
  • Mount Type: Equatorial or Altazimuth
  • Optical Design: Reflector or Refractor
  • Accessories: Eyepieces, Finderscope, Tripod
