  • The photometer can be connected via bluetooth to the smartphone app to display and to record your observations.
  • There are accelerometers included to provide the pointing of the photometer.
  • The inside battery is enough to register sporadic measures.
  • If you want to use it on the go or for a night long series of observations you should connect to a power bank.
  • Download and install TESS-P app for Android and record your measurements along with your GPS location.
  • You can also use this photometer to map the sky brightness from a moving vehicle.
TAS allows you to obtain all-sky brightness maps
  • The mount should be leveled and oriented to north.
  • After connecting to the TESS-P smartphone app you only need to press the small button to initiate the full automatic scanning.
  • The 140 data point all along the celestial vault are recorded and they are used to create a map.
  • The all-sky night sky brighness map is similar to those of the NixNox Project.
  • Optional watertight case for outdoor and transport protection
