Sky-Watcher N-130/650 (BKP130/650) OTAW Dual Speed optical tube (SKU: SW-1000) is a fast Newtonian reflector with a parabolic primary mirror with a diameter of 130 mm and a focal length of 650 mm. The model is equipped with a 2" Crayford focuser with a 10:1 microfocuser, making precise focusing easier. The shortened tube design allows the primary focus to be moved outward, which makes focusing with a camera easier during prime focus astrophotography.
