Second hand GSO 4 piece colour filter kit in excellent condition. All filters are nice and clean with no marks or blemishes. Each come complete with their own bolt case. The orange filter has no markings on it hence the price, but still the same quality as the rest of them. A nice little kit for the avid observer.
Second hand Meade ND96 moon filter 1.25". This is the Japanese production so the quality is much higher than the standard filters. Allows you to observe the moon comfortably whilst bringing out detail on the surface and craters.
