This one is a complete mystery, but you get a BARGAIN! We know nothing about this except:
1) It's a light pollution filter of some kind; and
2) It screws directly into the back of your SCT.
That's it. That's the sum total of what we know. Brand? No idea; it's unmarked. Age? No idea. What wavelengths it filters out? Your guess is as good as ours.
It's in very good condition, with clean optics showing some signs of use, and an unmarked body. Take a chance!
