A visually stunning, robust telescope. Perfect for the traveling astronomer. The 106mm Apochromat telescope is a dream come true for both astrophotography enthusiasts and visual observers who are seeking the utmost in contrast. With it’s slightly over 4-inch aperture, this telescope offers both portability and exceptional brightness.

The high quality triplet lens delivers a remarkably sharp image thanks to the utilizations of Hoya’s FCD100 ED  glass, known for it’s minimal color aberration, crafted in Japan. This combination ensures the ability to capture razor-sharp planetary observations and produce breathtaking astrophotographs.
