I have a set of three Schuler narrowband filters for sale. These filters are in perfect condition. The OIII and SII filters have never been mounted; boxes opened only for inspection. The H-a filter has been installed in my CFW8. It is perfectly clean and the surface has never been touched with a finger or cleaned.
NOTE: The photo below of the single filter is the OIII.
These flters are $169 each new. I will sell the set shipped for $425.
