Starlight Xpress Motorized Filter Wheel 7 x 1.25 inch Filters (M28.5 threaded) – T2 Connection

Starlight Xpress Motorized Filter Wheel 7 x 1.25 inch filters (M28.5 threaded) – T2 Connection (SXUFW-1S)

The USB filter wheel was first introduced in 2009 and adds many new features to a useful imaging accessory. It is unique in that it does not require a separate power supply when used with USB control – the high performance DC gear motor runs entirely from the USB supply and consumes less than 100mA. It is also capable of operation from a serial input, or from a switched hand controller, both of which power the wheel from a small dry battery.

Major features:

Super-Slim Off-Axis guide head add-on! This useful filter wheel accessory makes accurate, flexure-free guiding easy to achieve. The extremely slim assembly screws directly to the wheel face and adds only 13mm to the back focal distance of the wheel.

The wheel is unique as it does not require a separate power supply when used with USB control – the high performance DC gear motor runs entirely from the USB supply and consumes less than 100 mA. It is also capable of operation from a switched hand controller, which powers the wheel from small dry batteries (4x AAA cells).

The wheel is light and slim, with an easy change system of thumbscrews to swap filter disks without tools. A variety of threaded adapters is available, they can be swapped by using a small screwdriver to release three stainless screws and lifting off the adapter flange. Each flange can be rotated to any angle before locking down, so that you can orient the wheel and camera into the optimum 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.

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.
