The Cassini Four (4) Slot Filter Wheel is another innovative device for telescopes from Cassini. Filtering out certain bands of light can be very useful when observing astronomical objects. Normally to use filters with your telescope you would have to thread the filters on and off of your eyepieces as you are use them. With the Cassini Four (4) Slot Filter Wheel, you simply insert three (3) astronomical color filters of your choice, leaving the fourth slot empty for non-filtered viewing. Then insert your eyepiece, and to switch through the filters, just rotate the bezel on the Cassini Four (4) Slot Filter Wheel. Now you can switch eyepieces as you normally would without having to swap filters between them. The wheel uses universal 1.25-inch threaded filters so you can switch them out with other filters for more usability. Filters are sold separately from the filter wheel.
