This is an 'as new' used example of the outstanding TEC 140 Apochromat. It is a part exchange which will be available from late September when the owners new, larger telescope will be ready. Any interested parties should first contact us. A deposit will be required to secure the scope prior to it becoming available. It represents a £1200 saving compared to the cost of a new scope.

A 12month warranty will be offered with the scope.

The TEC 140 is a classic apochromtic telescope. It offers excellent light gathering capacity with compact size while offering outstanding optical quality. Its F7 focal ratio makes it well suited for imaging applications. When used with a front mounted D-ERF it is also well suited to solar observing and imaging.

Optics

The TEC 140 is an Aplanatic Oiled Triplet refractor using FPL-53 glass for the middle element. The colour correction is optimised for visual use with focus shift of less than 0..2% from 436nm to 1000nm. Calculated strehl for the e-line (546nm) is 0.99. Testing of lenses has shown that the average actual strehl is very close to this with RMS wavefront error of less than 1/50 wave.

The oiled design has only two air to glass surfaces which offers the possibility of a higher contrast image due to reduced light scatter and glare compared to some air spaced designs.

The telescope is supplied as standard from us with tube rings and case and the excellent Starlight Instruments 3.5" focuser which can cope with almost any camera load. The focuser may also be motorised for more demanding imaging applications.

This option includes rings, 9" Losmandy Plate and carrying handle but no case.
