Celestron NexGuide Bedienungsanleitung Seite 9

GETTING STARTED
• Noise Menu—This menu sets the cut-off value for the noise filter of the image sensor. The proper noise level differs
according to exposure time, so NexGuide provides independent noise level control for each exposure time and
automatically uses the corresponding noise level when you change the exposure time. Once this submenu is selected,
you will see the current cut-off value displayed in the text zone of the LCD and the image zone will continually refresh.
• If you see a short solid horizontal line in the upper or middle portion of the LCD's image area, the cut-off value
is too low and you should increase it until you can see reasonable amount of noise dots spread evenly in the
LCD's image area.
• If there is no noise spot in the image zone of the LCD, it might mean that the cut-off value is set too high.
This could reduce the NexGuide's ability to detect faint stars. Reduce the cut-off value until you can see
some noise dots diversify evenly in the image area.
• RESET Menu—Returns all settings back to their factory defaults.
