Takahashi - Mewlon 210 Dall-Kirkham Telescope on EM-11 USDIII Mount

The Mewlon Series of Dall-Kirkham Telescopes by Takahashi© combines refractor-like performance in
a larger folded optic reflector design.

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.
