OCTAL

Octal develops night sky observation experiences by using an open source spectrometer. This device takes qualitative and quantitative measures of light pollution in situ. Originally created by Public Lab, this spectrometer was modified to measure light pollution using a mobile phone in two ways; counting starts, and measuring the light spectrum. The data collected through the device is then analysed in the Octal workshops to determine and compare levels of light pollution in different urban areas... Our team and collaborators is composed by a group of volunteers experts in different fields.
