Filter, Light Pollution Reduction – UHC/LPR (#94123) – These filters are designed to
enhance your views of deep sky astronomical objects when viewed from urban areas. LPR
Filters selectively reduce the transmission of certain wavelength of light, specifically those
produced by artificial lights. This includes mercury and high and low pressure sodium vapor
lights. In addition, they also block unwanted natural light (sky glow) caused by neutral
oxygen emission in our atmosphere.

Sky Maps (#93722) – Celestron Sky Maps are the ideal teaching guide for learning
the night sky. You wouldn't set off on a road trip without a road map, and you
don't need to try to navigate the night sky without a map either. Even if you
already know your way around the major constellations, these maps can help you
locate all kinds of fascinating objects.
Vibration Suppression Pads (#93503) – These pads rest between the ground and
tripod feet of your telescope. They reduce the amplitude and vibration time of your
telescope when shaken by the wind or an accidental bump.
