Takahashi M-250 O.T.A.




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.
