This filter has been sitting in my eyepiece case for a few years now. It's time to move it on.
It does have some blemishes as you can see in the photo. They have developed while in storage. If you are going to be imaging through the filter, flats will take care of them. (if they in fact affect the image at all)
This 2" filter is worth $179 new.
I'm asking $95, delivered, in Australia.
