  • 8800

This item is out of stock but you can place an order now and we’ll ship when it becomes available.


These 1.25" threaded LRGB filters are optimized for CCD astrophotography.

The red filter has a band pass that cuts the infra-red wavelengths. These filters have minimal 1.1mm thickness, and sharp transmission cutoff off-band.

The following aspects have been most important for the design of the ZWO filterset:

  • simple image processing for the user
  • highest transmission (nearly 100%) for short exposure times
  • adjusted transmissions of the individual filters for optimal colour reproduction
  • the use of industry standards
