Practical dust cover for all types of telescopes. It protects the inside of the telescope from moisture and dust. It can be used both from the telescope's inlet side and to be installed at the end (where the cell of the main mirror in Newtons is located). The elastic band around the circumference ensures a secure attachment to the telescope's tube.
The covers come in three size variants • # 30A115 - diameters from 150 to 250 mm • # 30A116 - diameters from 270 to 360 mm • # 30A117 - diameters from 370 to 520 mm
