- +
-Click the "Connect" button. The status must change to "Connected" and indicate the current state of PHD. +
-{{ :en:documentation:phd6.png?200 |}} +
- +
-Initialize PHD as usual and start guiding. The state must change to "Guiding". +

- +
-==== Use the Lock shift function ==== +
- +
-This function allow you to keep your telescope pointed on a moving object while guiding on a star. +
- +

- +
-The dithering function let you apply a random offset to the guiding position to avoid to cumulate the sensor defects at the same position on every exposure. +
- +
-The function is disabled by default because this is normally done by the capture software between the exposure. The use this function from Skychart is only interesting if you take your pictures with a standalone camera or with a software that not support dithering. +
