Mount: a stable mount is vital to avoid shaky views.Design: it should be designed for tracking, allowing you to keep up with the fast motion of the ISS.

To effectively observe the ISS, your telescope should have certain key features. A reflector telescope is a suitable choice. Telescopes with good tracking capabilities are better for observing fast-moving objects like the ISS. If you’re new to the world of telescopes, read my articles geared toward amateur astronomers: Catadioptric telescopes combine both, using lenses and mirrors in their design. Refractor telescopes use lenses to gather and focus light, while reflector telescopes use mirrors. You can broadly classify telescopes into three categories: This section will discuss the types of telescopes and the recommended specifications for observing the ISS. When observing the International Space Station (ISS) with a telescope, having the right telescope with suitable specifications.

Visible from various locations worldwide, the ISS is the third brightest object in the night sky after the Moon and Venus. It is now the largest human-made object in outer space. Constructed with multiple pieces, astronauts assembled the ISS in space. The ISS is located about 250 miles above Earth’s surface, traveling at a staggering 17,500 mph. Many countries have joined forces to build it and utilize its resources. It serves as a home for astronauts and a lab for science experiments in microgravity. The International Space Station (ISS) is a large spacecraft orbiting Earth.
