0.5mm Ultra-Thin Low-Halo Astrophotography Clip Filter Series for Canon APS-C and BMPCC 6K and 6K pro Cameras

Lugging around equipment is not fun. Clip filters are a lightweight and compact way of fixing challenging lighting conditions. We have a wide range of internal clip filters specially designed for Canon APS-C and Blackmagic Pocket Cinema Camera 6K and 6K Pro 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!

Frequently Asked Questions

Which cameras is this astrophotography clip filter compatible with?
This Astrophotography Clip Filter is compatible with Canon APS-C cameras and Blackmagic Pocket Cinema Camera (BMPCC) 6K and 6K Pro. Please check the Supported Camera & Lens List for the full compatibility list before purchasing.

What is the minimum lens focal length required?
Astrophotography clip filters are only suitable for lenses 14mm and greater. Using them with shorter focal lengths may result in vignetting or other optical issues.

What is the difference between Astro Multispectra (MS) 0.5mm and 1.0mm?
Both versions enhance a broad range of nebula wavelengths for rich color astrophotography. The 0.5mm version features ultra-thin glass that further reduces the halo effect around bright stars compared to the standard 1.0mm version, making it the preferred choice for demanding astrophotography where star rendering quality is critical.

What is the difference between Astro Multispectra (MS), Duo-Narrowband, and Nightscape?
The Astro Multispectra (MS) enhances a broad range of nebula wavelengths for rich color astrophotography. The Duo-Narrowband targets H-alpha and OIII wavelengths for high-contrast nebula imaging under light-polluted skies. The Nightscape reduces artificial light pollution while preserving natural sky colors, ideal for landscape astrophotography.

What lenses are compatible with this clip filter on Canon APS-C cameras?
With Canon APS-C cameras, this clip filter can only be used with Canon EF lenses. Canon EOS M system users will need an EF-EOS M adapter to use our clip filters.

I received a filter labelled "Canon APS-C" but I have a BMPCC — is this correct?
Yes, this is correct. When you receive the filter it will be labelled as Canon APS-C, but it is fully compatible with your BMPCC 6K or 6K Pro camera.

Is this filter covered by a warranty?
Yes. STC offers the world's first warranty and repair service for clip-in filters. Please contact STC support for details.
