Astro Multispectra (MS) Filter

Our Multispectra filter blocks out most light pollution allowing you to take high contrast and natural color images of the Milky Way with an urban foreground. Perfect creators seeking to for urban nighttime time-lapse.

Urban light pollution results in social inequity not only in low and mid-income neighborhoods but creates underrepresentation in the fields of astronomy and physics. As a BIPOC owned business, we wanted to help correct the underrepresentation.

In collaboration with astronomers and astrophysicists at Taiwan's famed Academic Sinica Research University and other researchers around the world, we developed a new light filter to block urban light pollution so Astro enthusiasts in the BIPOC community can capture and be inspired by a richer view of the universe.



  • Blocks urban light pollution by targeting specific frequencies by using ion beam-assisted deposition (IBAD).
  • Clear images when shooting at 8K and with 1200mm high-magnification telescope lens due to the super flat design.
  • 2mm Schott B270 optical glass prevents fogging by absorbing and quickly dissipating heat.
  • Double-sided anti-smudge nano-coating is hydrophobic stopping moisture and mold.
  • Antistatic coating keeps dust and fibers away.
  • CNC machined anodized aluminum eliminates surface reflection to avoid glare and ghost images.
  • Aluminum rim treated with Teflon and black matte finish making it non-slip and easy to remove.
  • Fits lens caps of all makes.
  • Can be used with STC’s Astro-AdapterM48-M56 astronomical lens adapterring, 0.75mm Pitch (sold separately).
  • Covered by the world's first global warranty and repair service for filters.
