I have for sale an Astronomik 12nm OIII filter in a 1.25" size that I bought recently and used on one evening, but it's a little too broad for me living so close to the CBD (it'd probably suit someone in the suburbs). It's therefore in as-new condition. These retail at $199.
I'm looking for $150 + post. PM me for more info.
Cheers,
Dunk
