For EAF Installation

This SV550 122 APO is compatible with EAF focuser. To install the EAF, first you should remove the screw completely as shown. Then look inside the hole and slowly rotate the focuser until you see another set screw inside the hole. This screw actually secures the focusing knob to the shaft. Insert a wrench and loosen this screw. Note that there may be two of these screws, so rotate the focusing shaft one turn to be sure. The focus knob will slide off after that.
