APO140FL F/9.6

Description

Our dedicated Planetary Refractor, the APO140FL F/9.6 will open the night sky to those willing to observe.

• The APO140FL F/9.6 features an air-spaced apochromatic-doublet objective with a Fluorite (CaF2) rear element that results in a lighter objective.
• The objective weighs about 2.5 lbs., compared to 5 lbs. for the APO140FL F/7 version, allowing it to come to temperature more quickly.
• Starting 2025, the objective includes anti-reflective and hydrophobic coatings for easier cleaning and maintenance.
• Housed in an aluminum cell, it provides excellent thermoregulation while remaining lightweight and strong.
• The optical assembly is inside a lightweight aluminum tube with sharp-edged baffles.
• No collimation is needed after the scope leaves TEC.
• Comes equipped with a Starlight Instruments FTF#2545 Feather Touch Focuser with coarse and fine 9:1 planetary reduction.
• The 2" locking metal collet is temperature-insensitive and holds loads with precision and concentricity.

In classic refractor fashion, the TEC APO140FL F/9.6 is a no-compromise, no-frills design that lets the wonders of nature speak for themselves.

Price: $7,500 (including an initial $2,500 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.
