3-10 If necessary, operate the joystick corresponding to the diurnal movement
(earth's rotation) of the star.
* In the case where the mode of the joystick is in the erect-image mode, an
image that is seen will move to an opposite direction of side-to-side and up and
down from where the joystick is tilted. (Refer to the page of Three Modes)
* Since observation of the universe may not require an erect image, images that
can be seen with VIPER are reversed from side to side (using eyepiece:
diagonal mirror) and upside down 180 degrees rotated (using eyepiece:
straight-through). It is possible to observe a normal erect image, if a terrestrial
erect-image diagonal (optionally supplied) is attached.
