bendiddley Posted November 4, 2022 Share Posted November 4, 2022 Now that most street lights are LED, I'm wondering if light pollution filters are still needed as I was under the assumption that they only filter out the old orange sodium lights?

Philip R Posted November 4, 2022 Share Posted November 4, 2022 (edited) Unfortunately they [ie 'traditional' LPR filters] don't work is the simple answer. LED streetlighting gives off too much at the 'blue end' of the visible spectrum. Using a neodymium, UHC or Olll filter should improve your viewing. The Olll maybe overkill on small aperture ‘scopes.
