The Takahashi Mewlon Series of Dall-Kirkham Telescopes by Takahashi combines refractor-like performance in a larger folded optic reflector design.  The Mewlon series comes in three objective diameters:  210 mm, 250 mm and 300 mm.  This revolutionary design has set the standard in folded optic systems.

The precision optical surfaces of the Mewlon series is at least λ/20.  This results a highly concentrated airy disc, resulting in pin point star images and high contrast fields.  The primary mirror is installed in a specially designed mirror cell that is designed to reduce astigmatism.

Please Note : Mount and tripod not included.
