Extension tube for RC telescopes with 6" and 8" apertures, 25mm

RC telescopes have a long distance between the rear of the tube and the focus to allow the use of off-axis guiders, focal reducers or filter wheels. However, this distance is often not needed, and the focuser must then be extended completely to reach the focal point. This leads to an unfavourable leverage effect on the focuser.
With this sleeve, you can adjust the distance for your accessories so that the focuser is in an optimal middle position, and there is no interference from excessively long levers.
