This manually controlled filter wheel has an easy to use turn dial to switch from filter to filter and a handy quick release door so that you can swap out filters without disturbing your set up.

Best Manual 5 Position Filter Wheel I've Used ...
The Celestron Skyris manual five-position filter wheel is constructed very well and is all aluminum, including the rotating wheel which is threaded for the filters. The front and back surfaces of the filter wheel case appear to have been routed to remove excess material to keep the weight down while retaining the strength to support the optical train without flexure. There is an oversized access hatch to easily change filters without having to disassemble the filter wheel. The inside depth of the wheel accommodates the SA100 grating for low resolution spectroscopy of point sources. The optical train in my setup is a 9.25” sct, a focal reducer, an off-axis guider, the filter wheel, and imaging camera. The focal reducer to CCD distance is ~140 mm and the grating to CCD distance is 55 mm, yielding 11.7 Angstroms per each 6.45 micron pixel. Thus, the filter wheel makes it a snap to go from spectroscopy to imaging with narrow band filters at a plate scale of 1.12 arc seconds per pixel.
