The APO140FL F/7 is TEC’s most popular telescope. Weighing less than 20 lbs., the APO140FL F/7 is highly portable and accommodates a wide variety of accessories. The APO140FL F/7 is an excellent option for visual observation and CCD imaging.

1 天前 · Test TEC 140 ED (DPAC) - posted in Refractors : After a long time I pulled the TEC 140ED (year 2011) out of storage to compare it with the Askar 203mm, and on that occasion I did a little DPAC test. It is obvious that Yuri can do it! The optics are amazing even if not completely free of chromatic aberration, but the focus was on eliminating other optical defects.

2014年9月16日 · The 160 ED is all of the above in a slightly larger package. The views of Saturn and Jupiter just a little bit crisper. IMHO, the 160 ED was the best value in the TEC line. Financially the jump from the 140 to the 160 FL is a significant jump.

2023年12月6日 · The TEC 140 is a premium quality – and priced – instrument. It sits within several lines of refractor that TEC makes and the TEC140 is the second “lowest” of the line since they make a TEC 110 as well (110mm objective).

2025年1月6日 · I need feedback from TEC 140ED owners on focal reducer/correctors - posted in Experienced Deep Sky Imaging: I am currently considering both the TEC 0.9x FRC and Astro-Physics 0.72x Quad Telecompressor Corrector for purchase in …

This year (2015) we tested the TEC APO 140. This was the first TEC 140 tested by Airylab and one of the rare professional lab-independant-test made with a TEC140... Airylab uses an Shack-Hartmann (HASO tm) analyser. The results are impressive and match my own Roddier test with a nice 0.975 Strehl in the green (543nm).

The TEC APO140FL F/7 is a beautiful telescope at a beautiful price point. Built with precision from one of the industry's most trusted names in quality, TEC's APO140FL gives you more apochromatic aperture for your money than most any other premium telescope maker.
