Refractors

Refractors

Our selection of refractor telescopes covers the needs of serious observers and astrophotographers, from reliable beginner doublets to premium apochromatic refractor telescopes designed for demanding imaging setups. Thanks to their unobstructed optical design, refractors deliver exceptional contrast, pinpoint stars, and stable performance for both visual observation and deep-sky astrophotography.

  • Doublet & APO Triplet: Versatile wide-field refractors and fully color-corrected apochromatic objectives designed for high contrast, minimal chromatic aberration, and excellent performance as a refractor telescope for astrophotography.
  • Quadruplet, Quintuplet & Petzval: Advanced astrographs with integrated field correction, producing a flat imaging plane for modern large-format sensors without the need for external field flatteners.

We ship across Canada, the USA, and internationally, with knowledgeable support from passionate astronomers.
