Using a variety of different eyepiece filters is an effective way to enhance visual observations of the planets and Moon, and more distant deep-sky targets including nebulas, galaxies and star clusters. Usually, a single filter is attached to an eyepiece, then the combination of eyepiece and filter is inserted into a telescope focuser to achieve a filtered view. To change the filter, you would normally have to remove the eyepiece from the telescope, unthread and exchange the filter, then re-insert the eyepiece and adjust focus. This process can be a hassle, especially if you wish to use more than one 2" filter during a single stargazing session to compare filtration effects. The Arcturus 4-Slot 2" Filter Slider takes the hassle out of the process by allowing you to switch between up to four 2" filters quickly and easily.
