Adjusting explanation: Loosen two screws above the Holder, the CCD attachment may revolve 360°so as to adjust the direction of CCD; meanwhile loosen three screws of the annular knurl part, and revolved the annular knurl part, it can adjust the high and low on focus. The top three screws can be adjusted when the CCD target surface isn’t in the central
