Connecting Adapters to traditional Color Filter Wheels
All FLI traditional Color Filter Wheels accept FLI cameras directly. FLI Color Filter Wheels can be
mated with other types of cameras using various adapters.
Color Filter Wheels with body types 1 and 2 have covers that are threaded to mate with a standard
2-inch nosepiece common to many astronomical devices. The FLI DT -1 is a 2” Draw Tube shipped
with Color Filter Wheels that have body type 1 or 2. The DT-1 is typically mounted to the Color Filter
Wheel’s “telescope side.” Other adapters fit into the adapter pocket which is generally the Color Filter
Wheel’s “camera side.”
1.
Remove the Color Filter Wheel’s adapter pocket disk. Save this disk and replace the disk when
an adapter is not connected to prevent dust from entering the filter chamber.
2.
Place the V-groove side of the adapter into the aperture.
3.
Snug the screws using the provided hex wrench. The adapter should align itself during the
snugging procedure.

Remedy
The computer does not correctly identify
the attached Color Filter Wheel.
Check that the Color Filter Wheel’s power supply and USB cable are
properly connected. If so, follow the steps below.
1. On the FLI Filter dialogue box right click on the top of the
dialogue box and select “Communications Settings”.
2. On the new dialogue box select “Scan USB,” then click OK.
The system should display the correct number of positions.
3. Click Scan. The system should display “flifil0” or “flifil1.”
4. If a problem persists, unplug the Color Filter Wheel
power and USB cable, then reinstall FLI Filter.
A filter is not centered in the CFW aperture
In the FLI Filter dialogue box, click HOME. The CFW moves to place the
filter in position 0 in the aperture.
The filter pocket cup I want to see is not
displayed in the aperture.
On the FLI Filter dialogue box, click any button that identifies a filter
pocket/cup position to move that filter pocket/cup into the aperture
position.
