I have a Celestron #94127A, LPR Filter (Model B - for back threads of SCT's).
Light Pollution Reduction (LPR) Filters are designed to selectively reduce the transmission of certain wavelengths of light, specifically those produced by artificial light. This includes mercury, and both high and low pressure sodium vapor lights. In addition, it blocks unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. sky glow). As a result, Celestron LPR Filters darken the background sky, making deep-sky observation and photography of nebulae, star clusters and galaxies possible from urban areas. LPR Filters are not used for lunar, planetary or terrestrial photography. Fits rear cell of Celestron’s C5, C6, C8, C9.25, and C11 Telescopes as well as Meade 8, 10 & 12” with SC reduced rear cell adapter.
