TEC APO 140mm


TEC Triplet APO 140/980mm on Losmandy G-11 mount with optional tube rings and dovetail plate



One of the most excellent features of the TEC 140 Apo: The 3.5" Starlight Feathertouch focuser with 9:1 microfocuser

 Triplet APO 140/980mm - Highest Grade Optics - Top Mechanical Workmanship

The TEC 140 is the ultimate telescope for demanding amateurs looking for a most powerful, yet still portable apochromatic refractor. The telescope offers perfect images both on the optical centerline and off axis.

    		 oil-spaced aplanatic triplet objective with ED element. PV 1/20
    +
    		 Corrected from 436nm to 1000nm. Optimized for the e-line at 546nm
    +
    		 Residual chromatic aberration between 436nm and 656nm = 0.02% focal length
The Heart Of The TEC 140 - Oil-Spaced Triplet Objective

The TEC 140's objective is an oil-spaced triplet and completely free of reflections. With only two glass-to-air surfaces it offers a better light transmission than is possible in air-spaced objectives.

A high grade seven layer broadband anti-reflective coating (BBAR) is applied to each TEC 140.



Optical diagram of the TEC 140 Apo. The telescope offers excellent correction from 436 to 1000 nanometers. It was optimized for L546nm. Remaining chromatic aberration between 436 and 656nm is only 0.02% of the focal length.



Here you can see the excellent baffling and anti-reflective tube coating inside each TEC 140. Stray light is effectively reduced to practically zero.

Why Buy A TEC 140 APO Instead of Any Other Apochromat?

If you're in the Apo market you are looking for a telescope for a lifetime. Nothing else than the very best will satisfy your needs. This is why we recommend the TEC 140:

+
 it is large enough for serious deep sky use as well as top performance planetary and lunar observing.
+
 with the optional TEC field flattener or the less expensive TeleVue field flattener (recommended for standard DSLR cameras) the TEC is one of the most powerful telephoto lenses we know of. It will offer stunning photos of countless deep-sky objects
+
 it offers a decisively understated, elegant design
+
 it offers unparalleled mechanical quality. The focuser alone is a masterpiece in its own right.
+
 despite all this the telescope is still easily portable and is held sturdily by portable mounts. Our recommendations:
For visual use take the Losmandy GM8
For astro-imaging and other heavy duty applications take the Losmandy G-11
