Meade #500 Glass White Light Solar Filter (127mm)

Adapt your conventional nighttime telescope for safe solar viewing with Meade Instrument's #500 Glass White Light Solar Filter. Engineered to block 99.999% of intense light from the sun, it allows you to see sunspots, planetary transits, and all phases of solar eclipses. This version has a diameter of 5" (127mm) to fit Polaris 90 and StarNavigator NG 90 telescopes, and is held safely in-place by a simple thumbscrew for easy installation and removal without tools or permanent modification to your telescope. Remember to practice proper safe solar viewing techniques, and never look directly at the sun without certified solar viewing glasses and equipment.
