Takahashi’s CRS series of Mewlon telescopes leads the industry in advanced design and optical quality. At their heart is the Dall-Kirkham Cassegrain telescope design, coupled with a corrector that provides Ritchey–Chrétien like performance. With the CRS series, Takahashi has added a 3-element corrector plate made from ED glass, converting the telescope to a flat field instrument for imaging and visual observation. In addition, the CRS series has an electronic focusing system controllable with an ASCOM driver or in an autofocus mode. Each CRS telescope features a primary mirror cooled by 3 fans.
