TEC APO140FL 140 mm f/7 Fluorite Apochromat

TEC APO140FL 140 mm f/7 Fluorite Apochromat

TEC APO 140 - the most popular size of all TEC telescopes TEC (Telescope Engineering Company) is now available as fluorite apochromat.

It is for everyone´s needs. The scope is light weight, portable, and can be used for visual or CCD imaging. With the suitable field flatteners and reducers a world of possibilities is open to you. Due to its optical design, even solar observation is possible, whether with H-alpha filters or whitish light using a Herschel prism.

The objective is housed in an aluminum cell, providing for excellent thermoregulation properties while remaining lightweight and strong.

The optical assembly sits in a lightweight aluminum tube that utilizes anti-reflective coating and sharp-edged baffles throughout the interior and forget about collimation - after the scope leaves TEC, no adjustment is required.

Each APO140FL F/7 comes equipped with a Starlight Instruments FTF#3545 Feather Touch Focuser that was designed in collaboration with TEC. This is Starlight Instruments´ largest rotating focuser with coarse and fine focusing 9:1 planetary reduction assembly.

The 2" locking metal collet is insensitive to temperature fluctuations and holds loads with high precision and concentricity.

Able to accommodate a wide variety of eyepieces and mounts.

The previously already extraordinarily good device is now even better and convinces with an extraordinary color fidelity, which is in no way inferior to its larger siblings the 160 and 180 FL. Anyone who has ever been able to look through a genuine fluorite apochromatic will always remember the "crystal-clear", white image. Not to be neglected is the transmission, whereby fluorite is clearly superior to ED glass. While glass and ED glass (fluoride) still produce minimal stray light, no stray light can be detected with a fluorite element. The most impressive way to demonstrate this is with a green laser. The energy-rich green beam is clearly visible as a beam when it passes through all glass substrates - not only when it passes through the fluorite, as the laser beam remains invisible.

The TEC APO 140 FL has number of features that in a given combination are rarely found in one scope:

Precision apochromatic objective with modern coating that makes lenses almost invisible

Oil-spaced and fully sealed lens triplet, for fastest thermal adaptation and minimum of haze and reflections

Retractable dew shield

Lightweight tube assembly

Feather Touch 360° rotatable focuser with coarse and fine focusing

Collet type eyepice holder
