  • New OPTOLONG 2" UHC Nebula Filter for Cuts Light Pollution M48.5x0.75 Thread

    New OPTOLONG 2" Ultra High Contrast UHC Nebula Filter for Cuts Light Pollution. It does this by: Selectively reducing the transmission of wavelengths of light pollutants, specifically those produced by artificial lighting (including mercury vapor lamps, both high & low pressure sodium vapor lights, and the unwanted natural light caused by neutral oxygen emission in our atmosphere (i.e. skyglow)).

  • 2" UHC DeepSky Filter for Telescope eyepiece - Cuts light pollution - Astro

    The filter works by blocking the wavelengths or mercury and sodium-vapour used in urban lighting while letting the visible and H-Alpha emissions through. The UHC filter let the O-III and H beta lines through and through blocking the sky background it helps bring out details and contrast to planetary and gas nebulae.

  • New 2Pcs 2 inch' Polarizing Filter for sized 50.8mm Telescopes & Eyepiece No.3

    While observing the moon or planets, there is often too much light that washes out subtle details. This glare can be cut back using neutral density filters or polarizes. Polarizing filter is also helpful for splitting binary stars by reducing glare and diffraction around the brighter star of a binary pair.
