Telescope Accessories: Nebula (Nebular) Filters

Telescope Nebula Filters

Nebular filters, also called Light Pollution (LP or LPR) Reduction filters, are used to view faint, deep-sky objects in your telescope if you cannot access a dark-sky location outside of a city. They are a "nice-to-have" telescope accessory. If you can only pick one filter, get a narrowband filter. Be sure and get one that is labelled "UHC" or Ultra-High Contrast.
