Quick changes between different color filters can often reveal subtle differences in planetary atmospheres. A #47 violet filter, for example, sharpens clouds high in the atmosphere of Mars, while a #58 green filter penetrates more of the atmosphere, sharpening clouds closer to the surface. If a cloud on Mars appears sharper with a green filter, it is probably near the surface. If a violet filter gives superior definition, however, the cloud is at a higher altitude. Using the Lumicon multiple filter selector to quickly switch back and forth between filters often makes the sharpness difference much more visible. The Lumicon filter selector allows quick switching, something you can’t achieve by laboriously threading and unthreading filters in the chrome barrel of your eyepiece.

For tri-color CCD imaging, changing color filters between exposures is essential. Powered filter selectors are available that change filters automatically, but they are usually specific to certain brands of CCD cameras and cost many times the modest price of the Lumicon manual slide-type filter selector. The economical Lumicon filter selector will work with any CCD camera that uses 1.25" accessories.

Simply thread any standard 1.25" filters you choose into the filter slide (you can change filters or reorder their sequence any time you like). The selector has a 1.25" nosepiece that fits into your star diagonal. There’s a 1.25" eyepiece holder on the back side of the selector to hold your 1.25" eyepieces or CCD camera’s nosepiece. Simply push the filter slide back and forth to select the filter you want to use. The filter slides into the light path and securely clicks into place in line with your diagonal or camera. Stops at the ends of the filter slide keep the slide from falling out of the selector.
