You have dreamed of a reflector with exceptional and powerful optics, with a generous diameter and with the guarantee of an incredible contrast : Mewlon is for you!

With its Cassegrain range reflectors, based on Dall-Kirkham optical design, Takahashi acted as a pioneer, and made Schmidt-Cassegrain other manufacturers outdated. This reflector with its excellent optical qualities can be used in a wide range of applications, and brings it on the top of the market. No worldwide mass production of reflectors can be compared to the Mewlon and be able to offer similar performances : compactness, power, rationality and versatility.

Mewlon are available in 3 diameters (210mm, 250mm and 300mm), optical tube assemblies (OTAs) or associated with equatorial mountings.

The precision of optical surfaces is at least of ׯ/20. This standard of quality induces a strong concentration of the light in Airy disc, physical image of a star looked through any optical system. The stellar images are more defined and contrasted. The Mewlon primary mirror, oversized compared to the effective aperture, is installed in a mirror cell especially designed to avoid stresses sometimes generating of astigmatism.

The focuser, often one of the weak points of the current telescopes, was particularly neat. The translating mechanism of the primary mirror of Mewlon 180mm and 210mm is machined with a particular care in the Takahashi workshops in order to reduce the shifting, to obtain a softness and an optimal regularity of focusing. Mewlon 250mm and 300mm are equipped with a the secondary mirror translating focuser, ordered with an electric handbox.
Equipped with a 50.8mm eyepiece holder in standard, you will be able to associate the most appropriate accessory with it, for visual, photographic or CCD use. The complete and coherent range of accessories proposed, will reach any of your goals.

The fixing of Mewlon on equatorial mountings is carried out using functional and effective dovetails. Their design facilitates frequent handling such as balancing or OTA assembly/disassembly without deterioration. Moreover, on Mewlon of large diameters, a counterweight is provided to balance the optical tube.
Mewlon integrates a high quality finder scope, associating luminosity and sharpness. This finder scope can also be used as a handle for transportation, without creating any bending or malfunctioning.

Mewlon are Cassegrain reflectors using the Dall-Kirkham optical design. The elliptic primary mirror is associated with a spherical secondary mirror. The image is returned to the back of the instrument via an opening spared in the center of the primary mirror.
