    AstroCTC

    AstroCTC

    AstroCTC - Linux astronomy software for Planetary and Lunar image c

    AstroCTC (Astronomy CCD in Telescope Capture) is an application designed for video and image capture of the Planets and the Moon. A suitable astronomy or modified webcam will give the best results, however it will work with most webcams. The camera driver must be V4L2 compliant. Numerous video and image formats are available, however FITS image support is mostly basic and should only be used by those familiar with it. AstroCTC is intended for use with Linux only. While AstroCTC is primarily designed for use in astronomy, it can also serve as a general webcam program. The sample images shown were captured using a Meade LX90 8" and a Celestron NexImage camera.
