Description

Our largest portable refractor, the APO180FL F/7 allows the observer to delve deep into the beauty of space.

The APO180FL F/7 features an oil-spaced apochromatic-triplet objective with a Fluorite (CaF2) middle element, resulting in color correction that is optimized for visual use and imaging. This oil-spaced triplet design, in combination with multi-layer coatings on all surfaces of the objective, ensures maximal light transmission.

The objective is housed in an aluminum cell, providing 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.

The crisp all-white assembly projects the elegant, handcrafted quality that TEC is known for. Expect deep contrast and rich, natural color from this compact and timeless design.

Each APO180FL F/7 comes equipped with:

A Starlight Instruments FTF#3545 Feather Touch Focuser, designed in collaboration with TEC.
Starlight Instruments’ largest rotating focuser with coarse and fine focusing (9:1 Planetary Reduction Assembly).
A 2" locking metal collet that is insensitive to temperature fluctuations and holds loads with high precision and concentricity.
A focuser wheel for easy mount installation and direction.

Available for in-person viewing at the Company 7 Showroom in Maryland, USA.

In classic refractor fashion, the TEC APO180FL F/7 is a no-compromise, no-frills design that lets the wonders of nature speak for themselves.

Price: $19,000 (including an initial $6,000 refundable deposit).

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. Rest assured that your telescope has been optimized to be as optically perfect as possible. If the objective does not reach 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.
