The Yellow Submarine has surfaced. TEC's newly released update to the classic APO160FL will feature key design changes to optimize color correction and will be known as a “super” planetary telescope.

It will use an air-spaced doublet design and longer focal ratio to delve deeper into the skies and will shine in the night with its beautiful golden color. Yuri says, “it is about bring back the beauty of long refractors to your backyards, public clubs, school observatories, etc.”

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 interferomerical 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.



Our dedicated Planetary Refractor, the APO160FL F/11 will open the night sky to those willing to observe. 

  • The APO160FL F/11 will feature an air-spaced apochromatic-doublet objective with a Fluorite (CaF2) inner element that will come to temperature more quickly than the APO160FL F/7 version. 
  • The objective will be housed in an aluminum cell, providing for excellent thermoregulation properties while remaining lightweight and strong.
  • The optical assembly will sit 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.
  • Further, the beautiful black and gold assembly projects the elegant, handcrafted quality that TEC is known for. Expect deep contrast and rich, natural color out of this compact and timeless design.
  • Each APO160FL F/11 will come 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.
  • The APO160FL F/11 doublet will come with a 300mm plate and handle that will be directly attached to the telescope flanges. An optional plate could be used to give a larger balancing range for the telescope.
  • Able to accommodate a wide variety of eyepieces.
  • Recommended to be paired with a high capacity load mount and a stationary observation station.
  • TEC recommends the 10Micron GM2000 HPS, 10Micron AZ2000 HPS and the Astro-Physics 1600GTO Mounts.

In classic refractor fashion, the TEC APO160FL F/11 is a no compromise, no frills design that lets the wonders of nature speak for themselves.
