Meade Series 4000 Color Filters permit observation and photography of planetary surface detail that is often virtually invisible without filtration. Choose the filter or filter set that best meet your needs and see what you have been missing! Use filters individually or stacked to achieve selective filtration of the visual color spectrum.
Manufactured from the finest optical glass, each filter has its color spectrum dyed into the glass instead of being done with inferior color coatings. All filters are anti-reflection coated on both sides of the glass for the highest performance. The filters have a clear aperture of 26mm and are threaded for and compatible with all standard 1.25" telescope eyepieces. The filters can also be stacked with each other. Each Series 4000 Filter is packed in a foam-fitted plastic case for secure long-term storage.
