Looks very nice Can't wait to test this out in the field. Maybe in the future you could even use the sensors to know where the phone is directed at. I don't think that you have to install each pakage one by one, I think you can just use "dpkg -i stellarium_0.10.3r4182-1_armel.deb" and after you get dependency error use "apt-get -f install", this will install all needed packages. When it's done it should be installed.
