The Skywatcher Evostar 72 ED DS Pro OTA refractor telescope features an apochromatic doublet optical system, with one low-dispersion ED glass element and one crown element made from Schott glass. Metallic anti-reflection coatings on the glass-to-air surfaces provide maximum light transmission of 99.5%, while the optical design limits chromatic aberration and helps produce a sharp image.
With a focal length of 420 mm and a 1:11 dual-speed focuser, it is designed as an astrograph for astrophotography. Its short focal length makes it suitable for wide-field imaging, travel and portable astrophotography, without requiring a heavy astronomical mount.
