The kid-friendly telescope is a folded refractor, F11, altitude-azimuth design and can be used to observe eclipses as well.Features:. 27 1.2" (700 mm) FL objective lens. 2 1.2" (61.7 mm) objective aperture stopped down to 2 1.4" (57 mm). 1.2" (12.5 mm) fully-coated FL Plossl field lens, four element with a 10 mm aperture. 0.75¿‹ field of view (1.5 solar diameters). 2.2 cm gnomon (¿}30¿‹) and 22 cm pinhole projection (¿}3¿‹) pointing aids.
