UNDER CONSTRUCTION

The Telescope Control plug-in allows Stellarium to control a telescope on a computerized mount (a "Go To" telescope) and offers a graphical user interface for setting up the connection.

It has been included as a static plug-in in Stellarium since version 0.10.3.

This page covers version 0.1.9, the one distributed with Stellarium 0.10.3 and 0.10.4.

Serial port
sets the serial port used by the telescope.
The list contains the default values for the first four serial ports. On Windows, these are COM1 to COM4, on Linux these are /dev/ttyS0 to /dev/ttyS3, on Mac OS X the list is empty as it names its ports in a peculiar way. On all three platforms the list can be edited and new values can be added. (If you are using a USB-to-serial adapter, the default serial port of your telescope most probably is not in the list.)
To list all valid serial port names in Mac OS X, open a terminal and type:
ls /dev/*
This will list all devices, the full name of your serial port should be somewhere in the list (for example, "/dev/cu.usbserial-FTDFZVMK").

User interface settings:

Field of view circles

A series of circles representing different fields of view can be added around the telescope marker. This is a relic from the times before the Oculars plug-in existed.

In the telescope configuration window, click on "User Interface Settings". Mark the "Show FOV circles" options, then enter a list of values separated with comas in the field below. The values are interpreted as degrees of arc.

This can be used in combination with the Stellarium Virtual Telescope to display a moving marker with the Telrad circles. In this case, the list of FOV values should be "0.5, 2, 4".

Sending commands

Once a telescope is successfully started/connected, Stellarium displays a telescope reticle labelled with the telescope's name on its current position in the sky. The reticle is an object like every other in Stellarium - it can be selected with the mouse, it can be tracked and it appears as an object in the Search window.

To send a "slew" command to the telescope, select an object (e.g. a star) and press the number of the telescope while holding down the Ctrl key. (For example, Ctrl+1 for telescope #1.)

As of version 0.1.9/Stellarium 0.10.4, there is no way to slew to a specific set of coordinates.
