## PHD Guiding

This panel contain the tools to interface with PHD2 Guiding.

The interface let you easily use the ““lock shift” function to keep your telescope pointed on a moving object while guiding on a star.

You can also activate the “dithering” function to apply a random offset to your guide position.

#### Connection to PHD

Start PHD2 and check that Tools / Enable server is checked.

In Skychart you can change the host on which PHD is running and the connexion port. If Skychart and PHD run on the same computer you can just keep the default values.

Click the “Connect” button. The status must change to “Connected” and indicate the current state of PHD.

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.

Click on a moving object in the map, for example an asteroid or comet. The object displacement in arcsec/hour is show.

To send this displacement rate to PHD click the “Set rate” button. The current PHD lock shift status is displayed to confirm the change.

To start the shifted guiding on the moving object click the “Off” button. The button text change to “On” and the PHD status change to “True”.

#### Use the Dithering function

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 of this function from Skychart is only interesting if you take your pictures with a standalone camera or with a software that not support dithering.

To activate the function, open the script configuration with the “Script” button.

Select the row “Event_0:0:Initialisation” and click the “Edit script” button.

#### Make the background chart

When ready press the “Set chart” button.

#### Make the rotating disk

Without changing anything press the “Set overlay” button.

#### Printing

Use the “Print to bitmap” function to save a large image file for both part. In Printer Setup, select “Bitmap file”, set width and height to a comfortable value depending on the size you want to print (something between 2000×2000 to 5000×5000 is a good starting point). When asked give a file name for each part.

If required you can use an image editor to make some adjustment or additions.

You can now print the background chart on paper or cardboard, and the rotating overlay on printable transparency film.

Finally cut the transparency, and perforate both at the marked pole location to mount with a small screw.
