    1515== Shooting sequence ==
    1616
    17 Dureing the shooting sequence, Papywizard executes the following steps:
     17(Only for hardware controlled shutters)
     18
     19=== Without mirror lockup ===
    1820
    1921 * move to the requested position
    20  * wait '''stabilizationDelay''' sec.
    21  * if '''mirror lockup''' flag is set, trigger the camera shutter for '''stabilizationDelay''' sec.
    22  * trigger the camera shutter for '''timeValue''' sec.
     22 * wait '''Stabilization delay''' sec
     23 * trigger the camera shutter
     24  * for '''Pulse Width high''' msec without '''Bulb mode'''
     25  * for ''''''Time value''' sec with '''Bulb mode'''
    2326 * move to the next position
    2427
    25 The '''stabilizationDelay''' value mainly depends of the camera/lens weight, and the size of the tripod. Using heavy camera and small tripod will take longer to stabilize than light camera and strong tripod. In practice, 0.1 to 0.5 sec. should be enough.

    27 The '''timeValue''' param should be computed so that the entire shooting sequence can complete. This includes:
     30The '''Time value''' param should be computed so that the entire shooting sequence can complete. This includes:
    2831
    29  * AF cycle
    30  * if '''mirror lockup''' flag is not set, time for mirror to lockup
     32 * AF cycle (not a good idea to use AF)
     33 * time for mirror to lockup
    3134 * exposure time
    32  * time for mirror to go back to initial position
     35 * time for mirror to go down
    3336 * time for writing buffer image to card
    3437
    3538The last 2 sequences can be included in the next move, but be sure that the camera is ready when the next shoot sequence begins!

    3960== Shooting direction ==
    … …  
    4263
    4364The best configuration mainly depends of the subject you are shooting. For example, if you have fast moving clouds, it is best to let the default configuration, to shoot the entire sky as fast as possible. But it also depends of the orientation of the head; if it is mounted on an horizontal pole, then choose column as first shooting direction.
    44 
    45 == Testing positions ==
    46 
    47 If the '''Time value''' parameter is set to 0, the head will skip the shooting sequence. This can be used to check all positions (new in 1.9.4).
