Freeing up space in my filter wheel for an H-beta filter in an attempt to see the Horsehead this year.
It's a nice general filter that works well on Mars, Jupiter and Saturn + the odd nebula.
The filter is in good condition and has spent its life in a ZWO filter wheel.
Comes with the original box and what I think are the original foam inlays.
