Handcrafted Custom Telescopes and Precision Optics

  • ULTRA LIGHTWEIGHT MOBILE TELESCOPE - AR GEMINI

    AR Gemini

    Our new telescope "Gemini" combines the advantages of the classic Dobsonian mount, but with an improved, lightweight and easy to assemble truss design.

  • ULTRA LIGHTWEIGHT MOBILE TELESCOPE

    AR 3T

    This model uses a specially designed triple pipe design. This truss design is a very lightweight and compact version of the Dobsonian telescope mount.

  • PRIMARY MIRRORS WITH A HIGH PRECISION PARABOLIC SURFACE

    Optics

    The mirrors for all of our models have an interferometric test certificate, which guarantees high quality. The Strehl ratio of the parabolic surface is above 95%

Interferometry

Interferometric tests conducted on each of our mirrors are a guarantee for their excellent quality. The results give an indication of product quality at multiple points over the entire surface, not just one. We also offer to do interferometric tests as a service.
