The "Telescope Engeneering Company" has long earned a reputation as a top-class telescope manufacturer. The family business in the US state of Colorado has been manufacturing telescopes of the highest quality in small series since the 1990s.
Before TEC manufactured the first refractors in the year 2000 (regular production of APO140 started in 2002), TEC were offering Sitall mirror sets from LOMO (upto 1.4m) and MAKs from 150mm to 300mm. The distribution of these products is stopped.
The three Petrunins are based on class instead of mass, therefore the delivery times are long! But the quality is also outstanding: TEC is one of the few manufacturers in the world that still masters durable oil-spaced triplet lenses. This results in particularly robust and stable optics that cool down very quickly and effectively. During the 15 years that Baader Planetarium has been importing TEC telescopes to Europe, only one oil-spaced lenses had to be renewed. We can therefore vouch for the quality and long-term stability of this oil-spaced lenses. Read more about the advantages of oil-spaced lenses for apochromatic triplet objective.
In years of work, TEC has now succeeded in manufacturing all device classes with a genuine Fluorite as a middle element. In...
Der TEC Okularrevolver ist optisch einwandfrei und macht mechanisch ebenso Spaß zu benutzen. Er dreht Ruck frei und klickt in der richtigen Stellung ein. Im Strahlengang sind Änderungen der Abbildungsqualität des Teleskops nicht erkennbar.

Okularklemmung sollte mit 2 Schrauben oder Baaderklemmung angefacht werden
Our company exists now for more than 50 years. In this time, more than 15.000 Baader Planetariums (the first patented product of our company) help all over the world to give students an understanding of astronomical correlations. In our own manufactory, more than 500 observatory domes have been produced and delivered turnkey-ready. Instruments and telescope accessories from "Baader" are known for their high qualities by many astronomers and universities. We consider it our duty and obligation, not only to sell telescopes, but an indivdually selected telescope system, that brings you a lifetime of joy.
