The Meade broadband nebular filter will greatly enhance your viewing pleasure. In fact itll provide a dramatic increase in visual and photographic details you can see in deep-space emission and reflection nebulae. It threads onto the rear cells of Meade LX-Series mirror-lens telescopes as well as to the rear cells of other Schmidt-Cassegrain scopes. This converts the telescope into a basic nebular mode for visual observing or for photography with a T-adapter or off-axis guider. Clear aperture is 36mm.

Visual useThis Meade Series 4000 nebular filter incorporates the very latest in interference coatings technology. Each filter includes more than 40 coating layers to reject with precision unwanted urban light pollution. At the same time it passes critical nebular emissions with minimal reduction. That means nebular light may be observed visually in dramatically increased detail while the effects of city lights are greatly reduced. Photographic useThe Meade broadband filter also leaves photographically-important hydrogen alpha nebular light at 656nm largely unattenuated. This makes the filter a valuable aid in photographing deep-space emission nebulae as well. Youll also note that views of galaxies are enhanced by the filter though not as dramatically.
