Starlight Xpress USB Filter Wheel
with 5 Position 50.8 mm Carousel - Female SCT Input - 72 mm Tak Male Output

The Starlight Xpress SXUFW-UM50.8TAK SX Filter Wheel comes with an internal five (5) position carousel that holds 50.8 mm unmounted filters. The input connection is an SCT female thread and the output connection is a 72 mm Takahashi male thread.

The SX USB Filter Wheel is lightweight with a slim profile. It is easy to change out filter carousels without the need for tools or a PhD. A nice selection of threaded adapters are available optionally, and can be changed by simply unscrewing three stainless steel screws with a small screwdriver and removing the adapter flange. You can rotate the flange to any position you like before tightening down the screws so that the filter wheel can sit in the best position for your imaging set-up.

The SX USB Filter Wheel is quiet in operation and 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.

A separate power supply is not required when you use the filter wheel with USB. The high performance DC gear motor uses less than 100mA and runs entirely from the USB supply. You can also operate the filter wheel from a serial input, or from a switched hand controller, both of which power the wheel from a small battery.

An optional “Super Slim Off-Axis Guide Head” can easily be added to the SX USB Filter Wheel. It screws into the wheel face and adds just 13 mm of back focus to the filter wheel.
