INDI QSI driver is available for download as a 3rd party driver from INDI's download page. Under Ubuntu, you can install it via:
sudo add-apt-repository ppa:mutlaqja/ppa
sudo apt-get update
sudo apt-get install indi-qsi
INDI QSI should be able to support all Quantum Scientific Imaging (QSI) 500/600 family of cameras & filter wheels in addition to autoguiding support, whenever applicable.
Once you're connected, you can capture images as FITS from the camera, control temperature, and set image binning and frame subset. The driver will automatically upload these images to the client in FITS format. If your camera is equipped with a filter wheel, you can control the position of the wheels and designate a name to each filter. For CCDs equipped with Off-Axis Guider (OAG), the driver supports pulse guiding.
There are no known bugs for this driver. If you found a bug, please report it at INDI's bug tracking system at SourceForge. (You can log in with a variety of existing accounts, including Google, Yahoo and OpenID.)
