Hi,
I bought it new from Bintel a couple of months ago, used it less than 10 times. But since I do 99% of my stargazing in North Sydney, no filter can darken the night sky except a thick dark cloud. So I might as well give up, especially with Vivid Sydney and endless other light shows going on.

Asking for $150 including postage.
Thanks for looking.
