Takahashi Mewlon-300CRS Dall-Kirkham OTA Telescope, TLK3502

The Mewlon-300CRS is the largest in 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 stepping motor control secondary focusing, which Takahashi first introduced in 1990, is now an advanced computer controllable focusing system. The focus system called Active Focus can be computer controlled by ASCOM compliant programs such as Focusmax and Maxim DL.

The Active Focus system, ASCOM compliant, enables the secondary focusing to be computer controlled by programs such as Focusmax and Maxim DL. This system includes backlash control as well. A hand control that can focus manually or with USB connector to a PC is included.

Additionally to aid cooling a low vibration three fan system in 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 operated either manually with the hand control or by PC. A convenient USB B connection is supplied 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 manual focusing. A free driver is used to enable computer controlled focusing.

The M-300CRS is a flat field corrected telescope that produces a flat field high contrast images and pinpoint star 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.

The Mewlon Series of Dall-Kirkham Telescopes by Takahashi combines refractor-like performance in a larger folded optic reflector design. The standard EM-200 or optional NJP mounts provide a stable, accurate platform for the M-210. The integral polar alignment telescope and R.A. axis level make accurate polar alignment to within 2 arc minutes of the celestial pole quick and easy. The reticle is designed to be used in either Hemisphere until the year 2030. No other manufacturer uses such a highly accurate polar telescope. The Mewlon series of Dall-Kirkham Cassegrain telescopes from Takahashi offer the experienced observer a level of performance and portability not found in other Cassegrain telescopes mass produced for amateurs. The classical Cassegrain telescope offers excellent performance, but they are extremely expensive to produce at large apertures. By concentrating on the Dall-Kirkham Cassegrains, the Mewlon telescope offers a professional level of performance within reach of most amateurs.

The Takahashi Corrected Mewlon employs an ellipsoidal figure on the primary mirror and a spherical figure on the secondary. By focusing on very tight tolerances for these surfaces, Takahashi is able to deliver a compact telescope with reasonable aperture and high resolution.
