I'm selling my only narrowband filter as I'm currently without an imaging set-up. I purchased the filter off a fellow IIS member back in December 2012 and it has lived in its filter case since 2014 when I regretfully sold my astrograph.
It comes in the original box but the hard plastic case that the filter sits in is from another filter.
The filter itself is in perfect condition as you can see from the attached photos.
Brand new these go for $400 so I'm asking $200 plus shipping if you're not in the Brisbane area.
