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 the12v DC OUT (13E, Fig. 1) and the RS232 port (13G, 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 obser- vation session to accelerate the temperature stabilization. As soon as the optics have reached an equilibrium with the environment the fan should be turned off by unplug- ging the fan power cord. 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.
