These are in perfect condition - only ever loaded into my filterwheel once, where they worked wonderfully for a couple of years, and then carefully unloaded back into their cases.
The 3nm ones are currently around $820 (USD$650) from OPT and probably closer to $900 when factoring in shipping.
The 5nm Ha is about $550 (USD$435).
I'll sell the 3nm OIII and 3nm SII filters for $540 each.
I'll sell the 5nm Ha for $400.
Inspections welcome if you're around Sydney's eastern suburbs. Happy to post at the buyers expense.
Bank transfer preferred but happy to take Paypal (though the buyer will have to cover the fees).
P.S.
Here are a couple of threads I posted when I got these filters showing the difference they made when imaging under the extreme light pollution of inner Sydney:
