PoleMaster compatibility
PolarShift is an independent project. Compatibility with the PoleMaster camera is implemented without affiliation with or endorsement by QHYCCD.
Astronomical data
The northern and southern polar catalogues are derived from HYG Database 4.1 by David Nash / Astronexus, under CC BY-SA 4.0.
ERFA 2.0.1
Astronomical coordinate calculations use ERFA 2.0.1. Its licence and non-endorsement terms are included with the application.
Open camera firmware
The native driver loads mikefsq/polemaster 0.1.0 firmware, licensed under MIT, into volatile Cypress FX2 memory. Disconnecting the camera erases it. The source provenance and licence are included with the application.
