Purchased this from Star Optics (now closed) to allow safe solar observing. I no longer own a 6" telescope to use this with. No marks and always handled carefully. Can be used for both visual and photographic use. Safely observe the upcoming total/partial solar eclipse with this quality filter. New retails for $175 AUD so grab a bargain for $125!
Pick up from Toowoomba Qld, can post for $15.
