Title says it all really.
This is a set of top quality dichoric (interference) LRGB filters, they are in excellent condition and were supplied by SBig with a filter wheel I have recently sold, new this set would cost you USD 495, see:

Make me an offer, if it is good one I will throw in a UHC filter and postage!
