Using object catalogs

Instead of typing in coordinates manually, you may select the coordinates from prepared catalogs or lists. The button list offers the following options:

• main $\longrightarrow$ guide: Offset the telescope to place a star centered in the main camera display into the GFOV of the guiding camera. The offset is done in rectascension. You may have to move the GFOV in declination to pick up the star (cf. Section 8.3.3).
• guide $\longrightarrow$ main: Reverse
• open: Allows you to enter your own catalog. Once selected this catalog is offered every time you press open. To close the catalog press close while the catalog is opened.
• bright stars: Provides a catalog of bright stars (V$<$7 mag).
• moving targets: Provides a catalog of Solar system targets

To select a star from a catalog and to position the telescope you have to press list and select the appropriate catalog. Browse through the catalog using the arrow keys (or the left mouse button and the scroll bar) and click with the left mouse button on the star selected. The coordinates of the star are entered into the buffer. Press exec to start moving the telescope.
