I had that trouble aligning it with the horizon. First remove your eyepiece so you see the image of the mirror against the sky, then pass your hand, a sheet of paper, a young child, or something in front of the lower part of the lightpath. When you look through the drawtube, you will see the partially obstructed lightpath. This will tell you where the bottom (hence horizon) is. Then align the ADC so it is parallel to the horizon. Replace eyepiece and away you go. If I was using a newtonian, or small SCT it would be dead easy because I could reach. For the C14 I made the horrible contraption in the attached image...
