Does anyone know how to get a red background with red letters on the Android keyboard ? The theme options either have dark background with white lettering, or bright background with dark lettering. This interferes with dark adaptation and makes night mode somewhat redundant. Thanks.

Depends on what version you're using Dave. As I say I'm still on version 0.12.5 because of my aging laptop, and the more recent versions are probably more intuitive. If you've any computer experience whatever this FAQ will set you on the right track I'm sure: https://github.com/Stellarium/stellarium/wiki/FAQ

Assuming you know about the Solar System plug in : https://github.com/Stellarium/stellarium/wiki/FAQ#Adding_a_comet_to_Stellarium_with_the_Solar_System_Editor_plugin Now on the newer versions you can possibly download the list of comets from there, but I have an older version and follow this procedure: Go to the MPC: https://minorplanetcenter.net//iau/MPEph/MPEph.html Put 46P in the object box Check the 'MPC 1-line' circle further down. Click 'Get ephemerides/HTML page' A text file will appear, which...

Yes it worked gzotti, many thanks!

Hello, Is it possible to add a comet which has not yet been published in MPC format, i.e. the new Comet Macholz: https://cgi.minorplanetcenter.net/cgi-bin/showobsorbs.cgi?Obj=DM001&orb=y Thanks.

I'm still using version 0.12.5 and Mars' current magnitude is given as -2.6, but all other sources say -2.8. The parameters such as distance and apparent size are correct however. I wonder is atmospheric extinction being taken into account here, although that's not actually stated on screen?
