The Cassini Color 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 Color Filter Wheel, you simply switch eyepieces as you normally would. To switch filters, just rotate the dial on the Cassini Color Filter Wheel. The C.F.W. has three filter settings: Nebula, Planetary and Clear. The Nebular filter is great for filtering out light pollution such as ground light. UHC (Ultra High Contrast) filters block a large fraction of light pollution, and bring out the details of planetary nebulae and most of emission nebulae under a dark sky. The Planetary filter is great for viewing the moon and planets by increasing contrast - helps to bring out dark surface detail on Jupiter and Saturn, darkens the maria on Mars, and improves visual detail when viewing Neptune and Uranus. 3rd slot - Empty to use additional filter of your choice or left empty so objects can be viewed normally without having to remove the Color Filter Wheel. Additionally the filters are universal 1.25 threaded filters so you can switch them out with other filters for more usability.
