Maksutov Fan
The Maksutov optics are equipped with a fan which will assist in the stabilization of
the temperature of these optics. The fan operates when a special power cord (sup-
plied in the accessory box) is plugged into the fan unit of the telescope and the12v DC
OUT (13E, Fig. 1) of the computer control panel with the power switch in the "ON"
position. The amount of time required to stabilize the temperature will be dependent
upon ambient conditions including the observation site and preexisting condition of
the telescope. The fan should be activated at the beginning of the observation ses-
sion to accelerate the temperature stabilization. As soon as the optics have reached
an equilibrium with the environment the fan should be turned off by unplugging the fan
power cord or by turning the power off in the AUX Port Power menu. Fan operation
time should range between 5 and 25 minutes. While it is permissible to run the fan
continuously it is not recommended because the very slight vibration of the fan may
cause noticeable movement of the objects observed in the sensitive optics.
