Special Projects

Description

TEC works regularly with Educational and Government Organizations to produce telescopes that are not offered to our typical clients. These include specialized designs for imaging and deep space observation, high volume orders, and extra-large objectives. All Educational and Government Organizations will receive a small discount on their invoice.

Individual buyers may also request customization to their telescope purchase. Each request is reviewed on a case by case basis, and requires either a detailed description and analysis of the customization, or sketches for elaboration. Customizations may incur additional fees or deposits depending on TEC’s availability and the elaboration of the design.

TEC is also a reseller of high quality Sitall Blank Mirrors from Russia. Our dealer in Russia specializes in mirrors a half meter or larger in diameter and requires several months from the time of purchase.

All Special Projects from TEC are reviewed on a case by case basis and may be adopted or denied based on a variety of factors. To inquire about starting a Special Project with TEC, please email us with the following; full contact information, the organization you are associated with, a detailed overview of the project, possible schematics, drawings, and dimensions, and the projected timeframe.

TEC will then review the information to determine the company’s availability to complete the project. Upon accepting the project, TEC may require a down payment to begin design and construction.

Focuser Information

Testing and Quality Assurance

TEC Telescopes go through rigorous testing to ensure top quality performance. Newtonian Rings are used throughout the glass production process and we then use an interferometer to correct any remaining imperfections. Every telescope is then tested vigorously to reach the most optimum Strehl ratio possible. If the objective does not meet Yuri’s expectations, the telescope will not be shipped. As a strict policy, TEC will not release telescope test reports.

While the objectives are fine-tuned under interferometrical control to meet the highest optical standards, cosmetic imperfections may exist in the objective and the tube assembly. Please rest assured that any imperfection in the telescope has been determined not to affect the optical performance.
