The Celestron Skyris 5-Position 1.25 Inch Filter Wheel allows the use of up to 5 different filters in conjunction with monochrome CCD cameras to achieve colour. Toggle between the 5 filter options while imaging without having to move your camera or telescope to reduce down time. If you do need to change a filter, there is a quick-release door to the internal carousel so that filters can be changed without removing the filter wheel. Made from machined aluminium construction & high-quality components including spring-loaded steel ball bearings, to give years of performance.A perfect complement to the Celestron Skyris monochrome CCD cameras, the wheel threads directly to the Skyris camera body. However, it's also compatible with a variety of other imaging cameras thanks to the included T-thread & C-thread adapters. Accepts most standard 1.25" format filters. Filters not included.
