PETG_ ZWO SeeStar S30 Coperchio tappo rugiada telescopio Bahtinov supporto filtro diffrazione

This is a Slim-fit friction-fit interchangeable version of the Seestar S30. I chose this design because it is the only way to block light bleed truly. This accessory set 3D_Print with PETG material is for users who want a more durable, higher-temperature-resistant, and less-brittle material than PLA.
