Optics Bresser AC 90/900:

This equipment is ideal for beginners, as well as for those amateur astronomers who know how to appreciate the details of a quality image obtained with a refractor . As it is an achromatic telescope, most color errors are negligible. The sharp, clear and almost lifelike images it provides speak for themselves.

Aperture ratio 1:10 ensures quality observation.

Summary of advantages:

  • Compact and easy to use refractor.
  • Less color differences.
  • Quality image.
