Chroma
Try the Astronomy filters professionals use at many major observatories, NASA and JPL – Chroma!
In business for 24 years and experienced in many scientific disciplines, Chroma has made filters for several US “famous name” companies, but now operates under its own banner in the Astronomy field.
Custom filters, in terms of size and bandpass, are a speciality!

Chroma H-Alpha 3nm Narrow Band Filter
H-alpha filters are essential for imaging nebulae and other objects which are rich in ionized hydrogen.
Chroma OIII 3nm Narrow Band Filter
OIII 3nm Narrow Band filters isolate the doublet emission of doubly ionized Oxygen.
Chroma SII 3nm Narrowband Filter
SII filters isolate the emission from ionized Sulfur atoms, also common in nebulae.
Chroma LRGB Filter Sets contain 4 x Individual Filters
- Luminance Red Green Blue
- Spectral performance has been improved for the Blue and Luminance filters and will be posted when data is available
Chroma H-Alpha 5nm Narrow Band Filter
The Chroma H-Alpha 5nm Filter is essential when imaging objects rich in ionised hydrogen, works well in light polluted areas and moonlit conditions.

This Jovian Methane Band Filter enhances contrast when imaging objects containing significant levels of methane.
Chroma Luminance Filter – New design to provide better images with modern sensors, especially when used with refractors.
Transmission between 420nm and 693nm is 96% to 99% and glass thickness is 3mm. Transmission data is from an actual filter and representative, but may vary very slightly between samples.
