Starlight Xpress USB filter Wheel


The Starlight Xpress USB Filter Wheel

The filter wheel with USB connection is a product developed since 2009 by Starlight Xpress that presents many new features for such an accessory. It does not require an external power source, as it is powered directly from the USB socket and consumes less than 100mA. In addition, it can also operate from the serial port or the manual control, in both cases powered by a small battery.

It can be rotated in both directions, before locking, allowing the wheel and camera to be placed in the optimal position.

The wheel is quiet in operation and the Hall-Effect 3 bit encoded positioning gives absolute filter locations (not serially sequential) so you can easily swap between any filters without accidentally losing the wheel position.
