USED Planetary Contrast Filters

The glass is surprisingly clean for a used filter, no scratches or coatings issues I can see. Screwed onto my eyepiece nice and snug, and Jupiter’s bands popped with way more definition than without it. Glad I grabbed one while they had stock left.

The contrast on Jupiter’s bands really popped through my 8-inch scope, and the glass itself had no visible scratches despite being used. Exactly what I needed for pulling out details on Mars too.

Got these for my planetary setup and the contrast on Jupiter's bands was noticeably sharper than with my old generic filters. The threads are clean and they screw on smoothly despite being used, which was my main concern.
