Use your computer and a software program such as TheSky, Deep Space, Guide, or Earth Centered Universe to see where your telescope is pointed. Move the scope until the cursor on the screen overlays the symbol for the object you want to look at. The small CTI box connects to your computer's RS-232 port and to two optical encoders on the R.A. and Dec. axes. The CTI itself has no display or object database. All this device does is take the encoder information and passes through to computer software (The Sky) It will not work in parallel with your BBox it replaces it. The supplied PC cable supports LX200,MAX,Ultima and BBox.
