2-Inch Extension Tube Kit with Parfocal Rings

This kit includes a 2-inch extension tube set with lengths of 5mm, 10mm, 20mm, and 30mm, designed for use with cameras and eyepieces. It also features a set of two parfocal rings for 2-inch eyepieces. The extension tubes help adjust the distance between the camera or eyepiece and the telescope, allowing for better focus and image positioning. The parfocal rings ensure that eyepieces remain in focus when switching between different lenses. The set provides versatile options for customizing your viewing setup, making it easier to achieve clear and sharp images during astronomical observations.
