Description

●The tube is attached with a 50.8mm sleeve, and four eyepieces with 31.7mm sleeves can be attached to the main body. The click-stop system allows you to easily switch between eyepieces.

●The eyepieces that can be attached are the LE series (excluding LE40/50) and the Abbe series. For eyepieces other than Takahashi products, use eyepieces of the same size.

●Do not attach eyepieces with thick and heavy barrels such as ultra-wide-angle eyepieces, as they may rotate under their own weight.

●In addition, due to the position of the internal prism, eyepieces with sleeve lengths longer than 31mm cannot be used as they may come into contact and be damaged.

●The optical path length of the four-headed turret revolver 31.7D is 82mm. When combined with the optional 50.8 extension tube S, the optical path length will be the same as that of the zenith mirror 50.8.

*The following models will not focus unless the 50.8 extension tube S is used.
