TUI:Telescope:Slew Window

This window lets you tell the telescope where to go.

• Name specifies the name of the object. It is only used for display and so is entirely optional. However, it can be helpful when looking through logs or the history menu or if you are sharing the telescope with other users.
• The position entry fields are sexagesimal. For the first field, please use caution as it can be in either hours or degrees, depending on the coordinate system.
• CSys specifies the coordinate system and (for FK4 and FK5) the date of equinox.
• Rot specifies the rotation angle and the type of rotation.
  
  
• Options: these checkboxes open or close panels of options. A given panel must be open for its settings to have any affect; If you change an option and then close the panel, the change will have no effect. The option panels are:
  • Mag PM: specify magnitude and proper motion
  • Drift Scan: start a drift scan or any great circle path of constant velocity
  • Keep Offsets: specify which offsets to retain
  • Calibrate: measure and correct pointing error
  • Axis Wrap: specify azimuth and rotator wrap preferences
  
  
  
• Status bar: just above the command buttons is a status bar which shows help and the state of the most recent command.
  
  
• Command buttons:
  • Slew button: initiates a slew to the position specified above.
  • Default button: resets all fields to their default values.
  • Catalog menu: contains objects in the users' catalog. Open... allows you to open a new catalog (replacing the current one). Selecting an object restores its settings; the telescope doesn't slew until you press the Slew button. Catalog objects with alt>0 are also shown in the Sky window. Warning: see Notes below.
  • History menu: shows slews you have issued from this window (most recent first). Select an entry to restore its settings; the telescope doesn't slew until you press the Slew button. Warning: see Notes below.
  • Stop button: halts the axes.

Notes:

• If an option panel is hidden then its settings are ignored.
• When you select an item from the History or Catalog menu, the proper motion and scan velocity panels are automatically opened if needed (so those settings can be used). However, you must manually open any other option panels if they contain special settings you want to use.
