Skywatcher Telescope Esprit-100ED Professional APO Triplet Astrograph with 100 mm Aperture (f/4.1)

Skywatcher Telescope Esprit-100ED Super APO Triplet Astrograph with 100 mm Aperture (f/4.1) !!!

Skywatcher Professional ESPRIT 3-Element ED apochromatic refractors are instruments of the highest quality with optical performance rivalling or exceeding similar telescopes of even the most famous high-end telescope brands.
Also the 100mm model is with 550mm f/5.5 (412mm f/4.1 with Riccardi reducer) still quite short and especially suitable for astrophotography. Without reducer, the instrument is also very well suited for visual observations. The plus in aperture is "rewarded" by more visible objects. The astrophotographer can resolve more details on smaller objects.
