Can you create a custom landscape in SkySafari 6 Pro like you can do in Stellarium? As in my backyard? That is the last feature I still use in Stellarium. If I can do that in SkySafari, I would have no need for Stellarium anymore. I tried to create a custom PNG in the "Horizons" folder, but SkySafari would not open on my Mac Pro with OS X after doing so.
