Jan, there's no need to ask (although it's a nice thing to do). You are free to re-use Stellarium's code as you see fit, so long as your license is compatible with ours. I don't think we removed the "and any later version" clause in the GPLv2, so I think you're good to use our code in a GPLv3 project. However, there are some portions of the code which are not strictly GPLv2 - some files in the planetephems library for example. Please see the specific license details in those source files.
