How do u make it spin from top horizontally ?

local target = workspace.IntCam.Head
local camera = workspace.CurrentCamera
camera.CameraSubject = target
local angle = 5

while wait() do 
    camera.CoordinateFrame = CFrame.new(target.Position)
                                  * CFrame.Angles(0,angle,0)
                                 * CFrame.new(0,0,-30)
angle = angle + math.rad(.6)

end

This script spins from left to right and goes on. I want this to spin from top horizontally how do i do this ? No matter what i change in my angles and mess with this doesn't work anyway.

This is how it rotates http://prntscr.com/bjj220 And this is how i want it to http://prntscr.com/bjj25j
