APT is able to control filter wheels via ASCOM drivers, INDIGO / INDIas well as SBIG filter wheels through their native interfaces. To describe the filter names and offsets in APT rather than in the wheel driver see Filter Wheel settings tab.
This section gives manual wheel control. Note that imaging plans can be configured to change the filters during the plan execution. See Plan Editor section.
The filter wheel connection is used or can be used by the following APT features:
When you connect an ASCOM / INDIGO / INDI filter wheel for the first time you will be asked to select the connection parameters from ASCOM or INDIGO / INDI selector dialog. APT will remember your selection and when you click again on the “Connect” button it will use the previous settings automatically. If you want to change the connection parameters, use “Shift+Click” on the Connect button. Use Ctrl+Click to forget the selected connection parameters.
To connect SBIG filter wheel see Select Camera Type. Note that for SBIG wheel you have to use the Filter Wheel settings tab to describe the installed filters.
To "connect" a manual filter wheel or filter drawer you have to enable the option in the Filter Wheel settings tab.
Opens the settings dialog of the ASCOM driver. If this action is not supported by the driver, use Shift+Click on Connect button and then click Properties in the driver selector dialog box.
List box with all installed filters that allows selecting directly the desired filter instead of scrolling. Note that Moravian Instruments filter wheels will make the actual movement before the next exposure.
When manual wheel or drawer is used, it just changes the select filter name after the filter is changed manually.
When is active (high-lighted) if there are entered focus offset for the filters in Filter Wheel settings tab or in the ASCOM properties and if there is connection to Focuser, then APT will adjust the focuser position on every filter change.
This option could be used even with manual wheel or drawer.
