CCDciel is free software released under the terms of the
GNU General Public License
CCDciel has all functionality required for advanced imaging of celestial objects including sequences for fully automated unattended operation.
For communication it uses the INDI and ASCOM standards. It can control the CCD/CMOS camera, focuser, filter wheel, rotator and telescope mount and uses image resolving software such astrometry.net for accurate positioning. It can serve both the beginner astro photographer as the advanced who can take a nap while the equipment is imaging.
You can use CCDciel on Windows, Mac OS X or Linux, but beware the program is still in beta version.
I use the Linux version every clear night so it is tested and must also work for you.
The Windows and Mac version must work but are not or rarely tested by me.
In any case I will appreciate your help for testing this software and reporting any bug or other problem.
The program documentation is now complete and a pdf version is included with the program.
