Tecnosky EDT Series – Apo Triplet Refractors for Astrophotography
The Tecnosky EDT Series represents the highest quality in apochromatic triplet refractors, designed for demanding visual observation and astrophotography. Each telescope in the line combines selected optics with precision-crafted mechanics to deliver sharp, high-contrast images free from chromatic aberration.
Why Choose a Tecnosky EDT
- Air-spaced triplet design with central FPL-51 element
- FMC coatings on all optical surfaces
- CNC-machined aluminum tubes with matte finish and retractable dew shield
- 2.5" or 3" rack-and-pinion focuser, stable and precise
- Compatible with reducers and flatteners for APS-C and full-frame sensors

FAQs about the Tecnosky EDT Series
What is the difference between a triplet and a doublet refractor?
A triplet refractor, like those in the Tecnosky EDT Series, uses three lenses to minimize chromatic aberration, offering sharper images than a doublet.
Which model is best for starting out in astrophotography?
The EDT 80 V2 is ideal for beginners: it’s compact, lightweight, and provides a wide field of view, perfect for extended objects like nebulae and galaxies—even with entry-level cameras.
Are EDT telescopes compatible with full-frame sensors?
Yes, all Tecnosky EDT models are compatible with full-frame sensors using the appropriate flatteners (1x or 0.8x). Proper backfocus and filter usage are recommended.
Which model is best for high-resolution visual observation?
The EDT 130 OWL is the top choice for visual observation of the Moon, planets, and double stars, thanks to its large aperture and high-quality FPL-51 triplet optics.
