I don't know (from experience) how to get the visuals, but don't ever try to "open" your astral "eyes", because you will end up opening your physical ones, and this will end the projection.
From the books, you can read the techs by Bruce etc, and the most effective one they say is to command "vision now !" loud and clear. Something may appear out of no-where, but I don't think it will be the real thing.
From some, I've learnt that it takes time and practice to be able to "see" in astral, just as an infant learns to see in physical after birth.
Those who are evolved enough (through past lives) can instantly see everything right at their first projection, and those who are newbies take time.
Energy levels also dictate what you see and if you see at all.
