    p3d

    p3d

    General data-reduction tool for fiber-fed integral-field spectrographs

    p3d is a general data-reduction tool for use with fiber-fed integral-field spectrographs (IFSs); although, the spectrum viewer works with spectrum data cubes of any origin. The tool is built about the proprietary software IDL (Harris/EXELIS; see http://www.harrisgeospatial.com), but can be used without any license. Most slowly running loops are implemented in parallelized C (OpenMP).

    libnexstar

    C API to control NexStar compatible telescopes

    This library implements the serial commands supported by the Celestron NexStar hand control (HC) and SkyWatcher/Orion SynScan HC. This applies to the Celestron: NexStar GPS, NexStar GPS-SA, NexStar iSeries, NexStar SE Series, NexStar GT, CPC, SLT, Advanced-VX, Advanced-GT, CGE, CGEM etc. SkyWatcher: EQ5, HEQ5, EQ6 (Pro), AZ-EQ5 GT, AZ-EQ6 GT, EQ8 etc. and the corresponding Orion mounts. Communication to the hand control is 9600 bits/sec, no parity and one stop bit via the RS-232 port on the base of the hand control. Communication can be established over TCP/IP if nexbridge is running on the computer connected to the telescope. To control network based telescopes nexbridge must be used on the remote site. https://sourceforge.net/projects/nexbridge/

    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.
