GoQat 2.1.4 is here!


GoQat is a hardware control and data acquisition program for astronomy on the Linux platform. It has an INDI client to operate any device with an INDI driver and offers fully integrated control of INDI CCD and autoguider cameras, autoguiding devices and filter wheels. It also has native support for any camera from Quantum Scientific Imaging and any Starlight Xpress USB 2.0 camera. It can also control Starlight Xpress filter wheels natively. GoQat can guide mounts via a serial/USB port, parallel port or autoguider port. In addition to LX200/Autostar telescope commands, GoQat also implements some features of the Losmandy Gemini system. Image streaming devices including webcams and frame-grabbers can be used for autoguiding or recording image sequences in SER file format. Focusing via Robofocus is fully supported. GoQat is multithreaded and tuned to give as smooth a performance as possible, even on single processor machines.

GoQat user interface


New in this release is the full integration of INDI autoguiding cameras and guide signals devices with GoQat's main functions. Focusers and telescope controllers will be fully integrated with GoQat in the next release. Using GoQat 2.1.4, you can:

  • Set the CCD temperature and filter for your CCD exposures, capture sub-frames and use binning.
  • Display real-time scrolling graphs of your CCD camera temperature.
  • Calibrate the autoguider with the camera at any angle with a single mouse-click.
  • Autoguide your exposures using the fully integrated autoguiding functions: CCD exposures automatically wait until the autoguider is ready.
  • Show real-time scrolling strip charts of star positions for periodic error analysis.
  • Focus your telescope automatically with robofocus, including 'V-curve' calibration, temperature compensated focusing and the ability to adjust focus according to defined offsets for each filter change.
  • Play back recorded video and automatically perform photometry and astrometry on each frame - ideal for asteroid occultations and other transient events.
  • Use task lists to control the operation of your telescope, CCD camera, autoguider and focuser completely unattended. GoQat can detect incoming tasks from a remote location and act accordingly.
  • Execute arbitrary scripts in the language of your choice, to perform any external operations that you can do with a script (e.g. live upload of images to a website) and to interact with and control GoQat.
  • Load and save Losmandy Gemini pointing model parameters and PEC data, and more.
