Price Reduced Sloan BVRI & C Photometry filters. All in fine condition with their original containers. Note: The B filter is a first generation and not suitable for VERY red stars (say B-I>5); otherwise would probably work well with 95-100% of the majority of observers observations. Essentially, you are getting the Clear filter for free at this set price. If serious photometry interest you might also want to check out the Schuler BVRI, Iz and C set listed under Filters, by me. These were all my 1.25 inch personal filters, by the way. Free Shipping in USA. FYI, if you are into really red stars you can toss this B filter and purchase the second generation one form Astrodon and you will still be saving over 40% of the cost of a new complete set!
The Filters have always been kept in a warm environment and remain as good as new, IMO.
