Welcome!

GoQat operates any CCD camera from Quantum Scientific Imaging or any Starlight Xpress USB 2.0 camera on the Linux platform. It can guide mounts via a serial/USB port, parallel port or autoguider port. Autoguider cameras include Starlight Xpress and video-for-linux devices such as webcams or frame-grabbers. GoQat implements some features of the Losmandy Gemini system and focusing via Robofocus is fully supported. GoQat has a standalone INDI client interface to operate any INDI devices - these will be fully integrated with GoQat's other functions in the next release. GoQat is multithreaded and tuned to give as smooth a performance as possible, even on single processor machines.

The QSI 532 analysis pages discuss in detail the performance of a QSI 532ws CCD camera employing the Kodak KAF-3200ME chip, including bias frames, dark signal, transfer curves, flat fields, residual bulk image and linearity.

The drift alignment pages take a detailed look at the standard method of polar alignment by declination drift, demonstrating how it works and showing the effects of refraction on polar alignment. A description of the polar drift method is also included.

The periodic error correction pages describe periodic error analysis and the generation of PEC instructions for programming a Losmandy Gemini controller using a scilab script.
