APO200FL F/11

Description

Our dedicated Planetary Refractor, the APO200FL F/11 will open the night sky to those willing to observe.

• The APO200FL F/11 features an air-spaced apochromatic-doublet objective with a Fluorite (CaF2) inner element that comes to temperature more quickly than the previous APO200FL F/8 version.
• The objective is housed in an aluminum cell, offering excellent thermoregulation while remaining lightweight and strong.
• The optical assembly sits in a lightweight aluminum tube with anti-reflective coating and sharp-edged baffles throughout the interior.
• No collimation is needed after the scope leaves TEC.
• The crisp all-white assembly reflects the elegant, handcrafted quality TEC is known for.
• Expect deep contrast and rich, natural color from this compact and timeless design.
• Each APO200FL F/11 comes equipped with a Starlight Instruments FTF#3545 Feather Touch Focuser, 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 temperature-insensitive and holds loads with high precision and concentricity.
• The APO200FL F/11 can be mounted with a 19" Losmandy Plate and Handle that attach to brackets connected to the telescope flanges.
• Larger Losmandy Plates are recommended for a longer balancing range.
• TEC will purchase and install the required plate for shipping.

In classic refractor fashion, the TEC APO200FL F/11 is a no-compromise, no-frills design that lets the wonders of nature speak for themselves.

Price: $29,000 (including an initial $8,000 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. If the objective does not meet 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.
