Unofficial users manual

This manual was created as result of my experience with a brand new StarTracker.

Stars placement

Stars should be placed in at least two different levels. Distance between stars should be 1/10 of the stars height.

  • Stars must be installed in a fixed and permanent structure.
  • Stars need to be placed as randomly as possible.
  • Stars must be placed in different heights (at least two levels).
  • Stars must be well separated, on an average 1/10th the distance from the floor to the ceiling height.
  • For stars size, see table 1. Stars shall not be closer than 1/15th of the height or 5x their diameters (whichever is greater).
  • Stars should be clearly visible (no objects, cables, etc hiding them).
  • In your higher sensor/camera height, you should have approximately 30 stars visible thru the camera, and never less than 11.

StarTracker sensor have a 90 deg field of view.




Lens Encoders

You can use external lens bolt-on encoders or internal Digi lens. But never connect both at the same time.

When using external lens encoders operate Zoom and Focus from one end stop to the other follwing start-up. Do zoom and Focus separately. This process will calibrate lens encoders range end stops. You will need to repeat after each power cycle.



= Shortcuts

You can enable/disable keyboard shortcuts under Main->Shortcuts.

O Toggle on/off the optical sensor camera. S Save. R Reset/unload map. L Load A Refresh estimated star detection. Y Yes / confirm. N No / cancel. I Toggle on/off IMU (gyro). Esc Close current menu/cancel current operation.


Calibration guide

set Exposure

Adjust the exposure using trial and error. Go to Alg menu, set the exposure level to 0.4 as a starting point. Visibility is adjusted in Alg>Star Vis set to normal.

Set radius

Star radius detection is set automatically, but you can make your own adjustments on Alg->Star Rad with values between 3 and 15. Nominal value is 5.

Initial calibration

Tools needed:

  1. Measuring tape.
  2. Laser measuring device.
  3. Gaffer tape.


For best practice, designate a startup calibration area, it could be at any part of your studio where the StarTracker can see stars. It is advised to build a calibration rig as the one built in the picture.
