One side is equipped with inner threads that fit most standard Schmidt and Maksutov Cassegrain optical cylinders/tubes to furnish a safe and firm connection, hanging the heavy imaging accessories and eyepieces and diagonals won't cause flexing, which can meddle/interfere with unobstructed/clear views. It is made from lightweight and long-lasting/durable aluminum treated with a less-reflection matte dark anodized finish. A brass internal retention ring holds your eyepiece and different adornments immovably set up without checking or damaging them.
