Stellarium mobile

[CHRlS]

Hi, 

I've got Stellarium on my phone and was wondering what orientation I should have it set as. Currently I have no settings on for when I look at the sky using the naked eye, but when I look through a reflector, what should the flip view be? Horizontal, vertical or both? I would have tried to work it out myself tonight but it look as though it's going to be cloudy.

Thanks.
