The Sky-Watcher 130/900 Telescope

The brand Sky-Watcher is one of the best known brands among telescopes. The Sky-Watcher Explorer 130/900 telescope is one of the best-selling entry-level telescopes in the world.

This version has a focal length of 900mm, which is a value for a general observation. In addition to observations of the solar system such as the moon and the planets, you will be able to start observing the deep sky. Indeed, you will be able to observe nebulae, the best known constellations such as Orion, the Big Dipper or Cassiopée .

Example of what you will be able to observe with this telescope with all settings optimized:

This is the ideal telescope for the beginner who is willing to invest on a small budget ($200 to $250) but wants to start observing multiple objects in the night sky. This model can even be used by a child if accompanied by an adult.

The telescope will allow observation with a 260 magnification to observe the planets. Suffice to say that you may be impressed if you are used to observing the sky only with the naked eye.

The telescope is relatively easy to assemble, like all models of the Sky-Watcher brand for that matter. A counterweight is included with the mount and will allow the telescope to be balanced.

Advantages of the Sky-Watcher 130/900

  • Cost of the aperture ratio among the lowest on the market compared to other telescopes
  • Reasonably compact and portable

  • Very good for lunar and planetary observation.
  • Good for astrophotography deep sky (not as practical and more difficult to use than with a catadioptric lens).
  • Low optical aberration and provides very bright images.

The disadvantages of the Sky-Watcher 130/900

  • More fragile than refractors or catadioptrics and require more maintenance (such as collimation).
  • Generally not suitable for terrestrial observations.
  • Slight loss of light due to secondary (diagonal) obstruction to refractors.

In summary, this small reflector is the best telescope to use for beginners because it is suitable for observing all types of objects to start the both astronomy and astrophotography.

Finally, if you want to accompany the observation of the sky by taking photographs, the Sky-Watcher 150/750 will be more recommended.
