Page 3: Initial Installation
Use larger stars as ceiling height increases, with a proportionate increase in spacing. Accuracy is improved by applying stars at multiple ceiling heights. Use at least 10% height difference though this is less important below 4m (See Star Chart). 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 3 of 70...
Page 4 An example of a 5-metre-high ceiling. The stars are positioned randomly with ideal spacing across the ceiling and lighting grid. The reflective metal surfaces do not present a problem for the StarTracker sensor. 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 4 of 70...
Page 5 1m,the stars do not need to be of differing diameters. Density can increase on the lower duct; notice the random placement. Installation extends to the boundary of the studio giving ideal coverage. 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 5 of 70...
Page 6 StarTracker Max Manual A 5m high ceiling with a lighting grid at 4 metres. Average height is therefore 4.5 metres with ideal star size of 35mm. 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 6 of 70...
Page 7 In this 5m high studio installation there are far too many stars being compromised by cables in front of them, within 5cm. This should be avoided. Spacing on the truss is good. 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 7 of 70...
Page 8 Notice star placement on the air condition vent; almost any fixed structures are suitable for mounting stars. Avoid cable tangles as placing stars directly behind these will hide stars from almost any viewing angle rendering them useless to StarTracker. 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 8 of 70...
Page 9 StarTracker is tolerant allowing for continued operation. We recommend a minimum distance of 75cm between stars at a height of 10 metres, ideally placing stars at multiple heights to increase accuracy. 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 9 of 70...
Page 12: Start-Up Procedure
Ensure cables are connected correctly, particularly the ST sensor umbilical. Connect the PSU D-tap to the D-tap-to-ODU cable to power the StarTracker Max. Push the power button if the unit fails to boot. It can take 30 seconds for the software to load.

Stars could be reduced to a min of 50. If the background is an unusually bright Background, it could be increased to a max of 170. Usually 100 / 80 suffices. 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 18 of 70...
Page 19 Info: This measurement does not have to be down to centimeter precision. You can allow an error of 5-10%. Meaning if you have a ceiling of 10.78m and you type in 10m it is still ok. 2023 - 2024 © Mo-Sys Engineering Ltd. All rights reserved 19 of 70...
