This ad is for the standard SBIG color filters for the CFW-8 carousel which includes red, green, blue and clear. They are mounted in threaded cells ready to screw into the CFW-8 filter carousel. All filters are IR coated except for the clear. They are scratch free and very clean, never taken out of the CFW-8. Just to clarify, this is for the 4 filters only, no carousel or CFW-8. See the SBIG site for all the complete technical specs. Price is half the cost of new: $200 shipped to you in a clear, sealed filter holder (U.S.). Thank you.
PS: Image below: the green filter in the case looks kind of light blue there for some reason; it is definitely green seeing it in person.
