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 inlet side of the telescope and to be installed at the end (where the main mirror cell in Newtons is located). The elastic band around the perimeter ensures secure attachment to the telescope 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
