Install The Filter - QHYCCD QHYCFW3 Manual

Step 1 Install the filter
1. First, we unscrew the eight screws on the back of the filter wheel and open the filter wheel.
2. We put the frameless filter on the hole of the filter disc. We need the spacer to be placed in the
three circular grooves around the filter. The number of the spacer depends on the thickness of the
filter. Keep the gasket and filter thickness consistent. For example, a 0.5mm lens requires only a
∮2*4 red spacer (0.5mm thick), and a slightly larger spacer is placed over the placed spacer to cover
the edge of the filter. . To push a 1mm lens like this, you need 2 ∮ 2*4 red gasket gaskets. However,
the 2mm lens does not need to be padded, just use a slightly larger spacer to fix it.
3. Finally align the hole of the gasket with the standard lens fixing screw and tighten with a Phillips
screwdriver. Install the filter in turn using the above method, and you can successfully install the
filter on the filter tray.
