Product Description

Takahashi Mewlon 300CRS Dall-Kirkham Optical Tube Assembly

The Mewlon Series of Dall-Kirkham Telescopes by world-renowned TakahashiJapan combines refractor-like performance in a larger folded optic reflector design.
The Mewlon-300CRS is the largest of the Corrected Dall-Kirkhams made by Takahashi. The internal 3-element ED corrector transforms the M-300 into a corrected flat-field instrument. An integral pulse motor controls secondary focusing, and is considered among the most advanced computer controllable focusing systems available today. The focus system called Active Focus can be computer controlled by ASCOM compliant programs such as Focusmax and Maxim DL.

A free of charge ASCOM driver is available for free download from www.takahashijapan.com website. It enables the focus control and full control of the cooling system. Backlash control is also included to insure precise focus for imaging or visual applications. The M-300CRS includes the pulse motor controlled secondary focuser as standard equipment This new focuser is the successor to the step motor secondary focusing system introduced by Takahashi in 1990 and is still used on the Mewlon-250 and 300. Additionally, a hand control that can focus manually or with USB connector to a PC is included.

Further, to aid cooling a low vibration three fan system is standard equipment. This system uses three sensors: one on the mirror, a second inside the tube and a third outside the tube to properly measure ambient temperature which enables the cooling system to be operated either remotely with the hand control or by a PC through a convenient USB B connection that is provided on the hand controller for easy computer connection. For manual operation the fan button is pressed to turn on the cooling system. Focusing is powered by a 12v AC power supply for computer focusing or four AA batteries for hand unit focusing

The M-300CRS is a flat field corrected telescope that produces flat field, high contrast images and pinpoint star views across the entire field due to its three element ED permanent corrector. This is a perfect match for the new Takahashi UW flat field 90° eyepieces.
