Astrophotography Clip Filter Series for PENTAX Cameras

Lugging around equipment is not fun. Clip filters give creators the ability to address dynamic lighting conditions in a lightweight and compact manner. We have a wide range of internal clip filters specially designed for PENTAX cameras.

STC's patented clip filters are designed to eliminate common problems found with other clip filter manufacturers, specifically color shift around the edges of the frame when using wide-angle lenses. See the difference! 


  • Unlike our competitors, our clip filter frames are made from non-magnetic anodized 304(A2) stainless steel treated with Teflon to avoid equipment scratches.
  • Double-sided anti-smudge nano-coating is hydrophobic stopping moisture and mold.
  • Antistatic coating keeps dust and fibers away from the filter.
  • Covered by the world’s first warranty and repair service for filters.
