Double Magnification Version

      (Ordering Code: L 104 DV)

                                       

The optical system in this version consists of two matched 130 mm 
dia lenses together giving a power of 9D. This enables a relatively 
larger Field of View (130mm) despite the higher power. It may be 
noted that with the Increased Magnification Attachment one can get
a power of 10D, but the Field of View gets restricted to only 40 mm.
Double Magnification Version is recommended where increased 
magnification is required, but where the duration of viewing is 
limited. Whereas, for continuous, long duration viewing it is
advisable to use the other models.
