Description

Optically corrected 102mm (3-lens) triplet apochromatic, carbon tube and 2.5" HEXAFOC precision focuser.

In the field of small and medium apertures, apochromats are unsurpassed : in fact, these devices combine ease of transport and images with incredible contrasts and sharpness with multiple functions for astrophotography. In recent years, advances in glassmaking have made it possible to produce high-quality apochromatic systems for an ever-widening audience. With the new Explore Scientific FCD-100 CF Hex , this path has gone one step further still: The color purity achieved by this device sets new standards in this price range. The optics design achieves a polychromatic Strehl ratio of 0.97 - a value that represents maximum correction.

This fantastic apochromat is also very versatile: the fast f/7 focal ratio allows short exposure times in astrophotography, the always sharp images and the excellent contrast allow both to have an overview of larger objects such as the North Nebula America or the Andromeda Galaxy to carry out planetary observations with maximum sharpness. The appliance is extraordinarily light and compact - the anti-condensation cap can be stored easily and out of the way. The latest generation lenses worked with great care are the fundamental element for these telescopes that offer enjoyment at the highest level. In fact, this model is recommended not only as a travel telescope, but also for quick observations and astrophotography. Rounding off this versatile unit is the excellent 2.5" HEXAFOC focuser with 1:10 reduction . With the large 65mm diameter, even in astrophotography with larger chips there is no vignetting due to the focuser, as instead it often happens with smaller diameters.
