|Brand and Model:||Harry Siebert Binoviewer|
|Description:||Included are two 21mm eyepieces, and a removable 1.7x Barlow. |
Extremely well designed, the sealed casing protects all optics from impact, moisture or dust. The entire sealed unit is overlaid with vinyl or optional leather cover (cover for cosmetic reasons only). Works well with helical focusers since the shaft can rotate internally.
