    • Oiled triplet design for ultra efficient use of light combined with FPL-53 lens elements.
    • Retractable dew shield for ultra portability.
    • Round edged baffles reduce turbulence.

    TEC Optical Expertise and Professional Quality Refractors

    Telescope Engineering Company was started in 1994 as an optical subcontracting company and after 6 years, many Maksutov, zero-expansion Sitall LZOS blanks, and several mammoth optical projects including a 1.4M system for an observatory the began to hone their expertise in on refractor systems.

    Running their production in Golden, Colorado, TEC is operated by an adept team of optical engineers. Special attention is paid to every detail of their telescope design and every component is assembled and made in the USA.

    Warranty Information: All TEC product carries a lifetime warranty! If TEC made it or if it came with your telescope, then TEC will guarantee that it is free from defect or fault under normal use. The warranty is also fully transferrable to all future owners.

    Important Note: TEC produces all of their telescopes in very closely controlled batches which allows them to maintain a extreme level of quality control. Because they work on one model at a time and each run is done in predetermined quantities, they are able to accurately schedule deliveries. It is highly encouraged that customers put in their order as early as possible as runs often sell out and waiting to place an order could result in a longer waiting period. A 20% deposit is required for the 140mm however the deposit is only required when TEC tells OPT your optics are ready to be installed in a telescope. We will contact you at that time to finalize the order.
