 Section 14: Autoguiding
IMPORTANT NOTICE! Never use a telescope or spotting scope to look at the Sun! Observing the Sun, even for the shortest fraction of a second, will cause irreversible damage to your eye as well as physical damage to the telescope or spotting scope itself.
Note that this feature is separate from the standalone autoguiding features of the Pictor XT. (see manual Section 1).

To Autoguide:

1. Select Autoguide from the Camera Menu, then select the autoguiding mode. PictorView XT supports two modes of autoguiding: Guiding on the brightest object in the field of vision, and guiding on a selected object.

2. For guide on brightest: select guide on brightest. The camera will take an exposure, determine the brightest point, and begin guiding on it.

3. For user guide: The Pictor will take an image and display it, then prompt you to double click on the object you wish to guide on. After confirmation, the camera will then guiding on the selected object.

4. While autoguiding, a display will appear that shows each successive correction made by the Pictor. This will continue until you press the Stop Autoguiding button.

5. Note: The 416XT and 1616XT are not intended to be used as computer-controlled autoguiders.
