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 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. |
