High-correction 127mm triplet apochromat (three lenses) with carbon tube and 2.5" HEXAFOC precision focuser.

Apochromats are in the small to medium aperture range, the measure of all things: the combination of good portability, very high contrast and image sharpness with the excellent possibilities these devices offer for astrophotography, can't be beat here. Advances in glass manufacturing have made high-quality apochromats possible in recent years for ever-widening buyers. With the new Explore Scientific FCD-100 Carbon Hex , this development has reached another peak: The color purity of this device sets new standards in this price range. The optics design achieves a polystrehl of 0.97 - a value which represents the highest correction.
This excellent apochromat is a verwenbares versatile device: the fast aperture of f / 7.5 enables short exposure times for astrophotography, the high sharpness and excellent contrast make field observations , such as the North American nebula or Andromeda galaxy as possible as precision. planetary observations. The device is extremely light and compact - the protective cap can be inserted and the carbon fiber tube construction allows for significant weight savings compared to a metal tube. State-of-the-art eyewear and the most careful manufacturing have created telescopes that offer pure observation enjoyment at the highest level. Therefore, this telescope is not only recommended as an unrestricted travel telescope, but also for quick observing in between, as well as for astrophotography. The high-quality 2.5 "focuser with 1:10 reduction completes the picture of this all-round device - a clear diameter of 65 mm also occurs in astrophotography with larger chips without vignetting through the eyepiece as this can be the case with smaller diameters.
