The Site tab allows you to enter and/or verify information about your geographical coordinates and current time. This information is automatically added to the FITS header when a new image is acquired from the camera. Site location and time are also used when calculating planet positions and the altitude and azimuth of an object.
Site location can be loaded from the telescope driver, if available, by clicking the Load from Scope button. When Load from Scope is clicked and geographical coordinates are available from the telescope, the Latitude, Longitude and Elevation (m) edit boxes are set to read-only. Otherwise you can use them to enter your observatory's Latitude, Longitude, and Elevation (in meters) manually. The Latitude and Longitude fields can accept free-form input; you can enter decimal degrees; degrees and decimal minutes; or degrees, minutes, and decimal seconds. You can also adjust the individual degrees, minutes, and seconds fields by positioning the cursor on one and clicking the spin control (up/down) buttons.
MaxIm DL always labels a newly acquired image with date and time expressed in Universal Time, derived from the computer's clock. The Computer Universal Time field shows the current time, allowing you to verify that your computer clock and time zone are set appropriately. Similarly, the Telescope field reports the time as reported from the telescope, if it is available. If not, click "adjust" to open Windows' Date and Time control panel applet to make the necessary corrections.
