Tecnosky Apo 86/602mm F/7 Quad Series Refractor

New Tecnosky Quad Series Refractors
The new Tecnosky Quad Series represents excellence in four-element optical design, offering incredible quality and versatility.

The 86mm model, with an F/7 focal ratio, features a four-element Petzval optical system with double ED glass, ensuring exceptional chromatic correction and a perfectly flat field up to Full Frame format.

This refractor is perfect for astrophotographers and observers seeking superior image quality, both for visual observations and astronomical photography.

Constructed with a low-expansion aluminum tube, the telescope is equipped with internal baffles designed to eliminate unwanted reflections and scattered light, offering a sharp and contrasted image. The robust and precise construction makes this instrument ideal for long-exposure photography, even in high humidity and low-temperature conditions.

The 3.2" precision rack-and-pinion focuser ensures extremely fine adjustment, thanks to the micrometric knob, allowing perfect control of focus. The integrated 360° field rotator makes it easy to orient the camera for a perfect image composition, a feature particularly appreciated in astrophotography.

The CNC-machined rings are robust and refined, allowing for lateral mounting of astronomy accessories. They are raised to allow the tube to slide freely without risking the adjustment knobs touching the long Vixen bar provided. The convenient handle that connects the rings has an Arca Swiss mount and numerous threaded holes for attaching, for example, a guide telescope.

Thanks to the included adapters, the Tecnosky Quad Series is compatible with 2" and 1.25" eyepieces, and also offers mounting options for cameras with three different threads: M48, M54, and M68, ensuring maximum versatility and compatibility with a wide range of photographic accessories.

The Petzval design offers several practical advantages:

1. Visual and photographic use: It is an excellent refractor for both direct observation and photography, with a correctly flat field and no chromatic aberrations.

2. Easy backfocus: It doesn't require complex backfocus calculations, offering unmatched ease of use.

3. Compatibility with focal reducers: It accepts reducers like the 0.8X, reducing the focal length to 481mm with a fast F/5.6 focal ratio, perfect for capturing celestial objects in shorter times and with a wider field of view.

4. High optical and mechanical quality: This construction makes the telescope a reliable partner in any situation, providing outstanding performance for both visual observation at various magnifications and wide-field astrophotography.

5. Weighing only 5.1 kg and measuring just 470mm (with the retractable dew shield), it is easily mountable on compact equatorial mounts like iOptron CEM26, GEM28, or harmonic mounts HEM15 and HAE29, ensuring portability and stability even on the go.
