Tentatively Sold Schuler Photometry Filters
Price Reduced: Unique Collection of BVRI, Iz & Clear Filters by Schuler. All in fine condition with their original containers, except for the clear filter. Will not separate this collection! This is a rare opportunity for those doing variable star photometry with a CCD. Free Shipping if USA
These Filters have always been kept in a warm environment and remain as good as new, IMO. I further suspect that this opportunity might very well be the last opportunity for a Variable Star Observer to secure a set of Schuler Filter.
