Telescope Engineering TEC APO140FL 140mm F7 Triplet Refractor

$10,442.00

TEC’s most popular telescope. It fits everyone’s needs. This Telescope is light weight, portable, and is optimal for visual and CCD imaging. It is one of the best telescopes for its size on the market.

Owing homage to one of TEC’s earliest designs, the APO140ED, the APO140FL F/7debuted in 2017 and has quickly become TEC’s most popular model.

  • The APO140FL 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 ensure maximal light transmission.
  • 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.
  • Further, the crisp all white 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 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.

In classic refractor fashion, the TEC APO140FL F/7 is a no compromise, no frills design that lets the wonders of nature speak for themselves. The TEC APO140FL F/7 costs $6,600, including an initial $1,600 refundable deposit.


Recommended Accessories;

  • Precision adjustable Tube Rings
  • 9” Dovetail Plate and Carry Handle facilitate easy transportation and fit seamlessly with most mounts.
  • Focal Reducer Corrector converts the F/7 Ratio to F/6.2 with a 115mm back focus.
  • Compact Carry Case that eases transport between observation locations.
  • 10×60 Baader Vario Finderscope with a TEC Finder Bracket and Base for Telescope mounting.

Closure of Kingsway store

Dear Valued Customers,

We want to take a moment to update you on the recent developments at Markarian Fine Optics. As many of you know, we have done our best to provide you with our best service while struggling to keep up with the rising costs of business in Vancouver, but something had to change. That is why we are altering our business model.

As you are reading this we have closed our storefront at 1481 Kingsway. We are sorry for the inconvenience this may have caused some of you and we sincerely apologize for any disruption in our communications over the past few weeks. The Canada Post strike severely impacted our operations this past Christmas, and halted the necessary revenue that would usually carry us through to the spring. We have already secured a small private office space to continue our sales and repair services. While this means we will be unable to meet most of you in person for the foreseeable future, we will be doing everything possible to maintain our standards and remain in contact with all of you. In the meantime we will keep you updated on our progress and look to this space as our new path evolves.


Anyone needing to get in contact with us may continue to do so via our Email and telephone as you have done in the past because these will remain unchanged. Email will be the more reliable means of contact while we are setting up, but we anticipate the phones to be working again soon. For anyone needing these contacts they are listed below:


Email: info@markarianfineoptics.ca
Phone: (778) 657-5330

We appreciate your patience and understanding as we navigate this transition, and we apologize for any inconvenience this may have caused.

Thank you for your continued support. We look forward to reconnecting with you soon and continuing to provide you with the services you expect from us.

Best regards,
Markarian Fine Optics
