Skychart never need to run as administrator but this can break the configuration. ![]() Show a warning in window title if running as administrator. The resolution of the background image is now be limited to improve the performance if the screen is big or if there is not enough cpu core for processing. Improve magnitude filter for small FOV. INDI server and driver selection is now in the telescope connection box. Default comet element download is now from Allow to lock at the position set from the menu View/Position. Beware this not work with dash line when printing on Windows because of API limitation. Option to not filter the bright nebula by magnitude, only by size. Option to show only the celestial equator line. Separate label setting for Asteroid and Comet. Add update menu for Delta T and Jupiter GRS. Allow per chart observatory horizon profile. New button to Park/Unpark the ASCOM telescope. Set observatory coordinates from the telescope GPS, this set a "Telescope" observatory name and not override other settings. Calendar rise/set are always given to the astronomical horizon. This can be disabled in Setup/Observatory. ![]() Show the object rise and set time relative to the local horizon if a horizon file is loaded. New mosaic tool to prepare mosaic for image capture application. Allow to use HNSKY star catalog using the "290" format. Support for the new GAIA DR2 star catalog. It is now possible to use a telescope connected to a remote ASCOM Windows computer from Skychart running on Linux or macOS. Add direct connection to Alpaca telescope.

The -cddir option must point to the folder containing u4b/, not the individual data files. Run the program in a console to show the syntax help. You can download u4conv for Windows and Linux or get the source code. It also remove the streak by using the file streaklist.txt. The advantage of u4conv is it process all the files at a time, add the star identifier, a selected magnitude and the color index after the other data. Then convert the binary data on the DVD to ASCII text files using the include u4dump program or my u4conv program. See USNO UCAC page for more information and to get the script required to correct the binary data. You must first copy the DVD content to your disk to correct for the error with the high proper motion stars. This allow you to include more or less information for each star depending on your needs. If you have a copy of the UCAC4 DVD, or if you download the full u4b folder from the CDS or a web mirror, you can use Catgen to build your own catalog from the original data files. ![]()
