dark |
[-d] [-t] [-f] [-n]<tt> |

If the exposure time is larger then 60 seconds, automatic remnant removal is done before the exposure starts.
If the option [-f] (fast mode) is used, the prompt will be returned when the exposure time is over and before the readout begins.
If the option [-n] is used, there will be no automatic remnant removal. |
