ZWO LRGB 2 Inch Premium Filter Set
Best optical filters for advanced astrophotography enthusiasts.
Elevate your astrophotography with this premium LRGB filter set, designed for monochrome cameras. Capture stunning, accurate color images by combining individual exposures for red, green, blue, and luminance data. These filters offer balanced 1:1:1 RGB color weighting and feature precision passbands that minimize light pollution while allowing nebulae emissions. Enjoy high transmittance, multi-layer anti-reflection coatings, and an integrated infrared cutoff, eliminating the need for a separate IR-cut filter. The parfocal design ensures consistent focus across filters, streamlining your workflow for breathtaking celestial views.

Know before you buy
Yes, the filters are designed to be parfocal, meaning they share a consistent thickness. This allows you to switch between the L, R, G, and B filters during your imaging session with minimal to no refocusing required.
No, you do not. These filters feature a built-in infrared cutoff that blocks wavelengths from 700nm to 1100nm, ensuring your images remain clean and free from IR-related artifacts.
These are 2-inch mounted filters with M48x0.75 threads. They are designed to be compatible with most standard 2-inch filter wheels, including those manufactured by ZWO.
The set is engineered with a specific spectral gap between the green and red bands. This design choice helps minimize interference from common light pollution sources, resulting in better contrast for your deep-sky captures.
Each filter is fine-optically polished to 1/4 wave accuracy. This high level of precision ensures that the light path remains undistorted, maintaining the sharpness of your telescope's optics.
The filters are balanced to have approximate 1:1:1 weights, which simplifies your post-processing. This balance allows for more consistent color capture across the RGB channels, reducing the time you spend adjusting color levels during editing.
