Installation Instructions
Due to varying QC standards across camera brands, even models of the same brand may have manufacturing tolerances. If the internal filter frame doesn't fit properly, please contact STC support or headquarters. Do not force installation.
Disclaimer
STC's Clip-in filters are innovative and rely on the camera's internal structure for stability. Minor marks from installation may occur but do not affect camera functionality or warranty. STC will not cover these marks or offer compensation. Please consider this before purchasing if reselling your camera is a concern.

The STC Light Pollution Filter is engineered using Ion Beam-Assisted Deposition (IBAD), bonding hundreds of ultra-fine optical coating layers firmly and evenly onto premium SCHOTT® optical glass from Germany. This ensures precise separation of starlight from artificial light pollution for exceptionally clean, high-contrast astrophotography.
The filter accurately suppresses major sources of light pollution:
Even in city centers with heavy light pollution, you can capture clearer skies and more defined star points.
Perfect for objects featuring Hα red and OIII blue-green emissions, such as the Helix Nebula (NGC 7293).
Recommended for beginners and advanced astrophotographers alike.
All our filters use STC’s exclusive nanocoating technology for the best optical quality. Our Sensor Protector, Star Mist, Cine Mist, Neutral Density (ND), Astro (light pollution) series, IR-Pass (590nm/720nm/850nm), and UV-IR-Cut filters all carry a double-sided hydrophobic, anti-smudge and antistatic nanocoating to enhance or block transmission in all kinds of particular spectrums.
For users who need multiple filters from the same series, you can refer to our Aerospace-grade Metal Case, featuring an exclusive stackable storage box with shock-absorbing foam. Compact and pressure-resistant, it allows you to carry all your filters at once—perfect for lightweight travel and outdoor shooting.
