I'm selling my 2" Astronomik CLS filter. I used it when imaging with my DSLR and it did a good job of cutting out light pollution. I'm selling as I'm imaging narrowband with a CCD now and I'm not using it anymore.
Always kept in case when not in use, in perfect condition.
Same as this one:

I'm looking for $140. Pick up available from Sydney city or eastern subs or I'm happy to post but the buyer pays for postage.
