These haven't had much use as I upgraded from a DSLR to a QSI683-ws8. Scratch-free, and in their original cases.

1x Astronomik T-thread 12nm OIII filter $200
1x Astronomik T-thread 12nm SII filter $220

Together $350. Pick up in northern Brisbane, or free shipping to anywhere in Australia.

These filters come with T-threads on both sides, allowing you to attach them to a T-adapter, etc. and still present a T-thread on the other side. These are ideal for DSLRs and other cameras that use T-threads.

To buy new from OPT it would cost AU$388 for the SII and AU$348 for the OII (plus shipping).
