Meade 911B Nebular Filter. Closeout. Meade Series 4000 Nebular Filters incorporate the very latest in interference coatings technology. Each filter includes more than 40 coating layers to reject, with precision, unwanted light from urban light pollution while passing critical nebular emissions with minimal reduction. Improves visiblility on nebulae from light polluted environments such as cities.
Threads onto the rear cells of all Meade LX / LS / LT / ACF-series mirror-lens telescopes and onto Meade ED Apochromatic Refractors (using the Universal Thread Adapter), as well as to the rear cells of other Schmidt-Cassegrain brands that use a standard 2" x 24tpi male SCT thread. In this way the telescopes are converted into a basic "nebular mode," for visual observing or for photography with the T-Adapter or Off-Axis Guider.
Clear aperture is 36mm. Made in Japan.
Product carries full one year Meade factory limited warranty (within US/Canada only).
