GoQat operates any CCD camera and filter wheel with an INDI driver on the Linux platform. It also has native support for any camera from Quantum Scientific Imaging and any Starlight Xpress USB 2.0 camera or filter wheel. It can guide mounts via a serial/USB port, parallel port or autoguider port. Autoguider cameras include Starlight Xpress and QSI cameras 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 - autoguider cameras, focusers and telescope controllers will be fully integrated with GoQat's other functions in future releases. 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.
