Takahashi  Mewlon 180 牛卡式反射鏡


Mewlon 180PZ
complete


Mewlon 180 System with Mewlon 180, Dovetail, 7X50 Finder, P2Z Mount, Wooden Tripod W/Shimano Clamps, LE-24 eyepiece, & 1 ¼" Diagonal . 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.
