Scopium flexible dewcap (150 mm) can be used for catadioptric (e.g. SC, MC) binoculars, newtons and refractors.
The tube enclosing the optic is larger than the optic itself and may vary in size depending on the type of telescope. The Scopium flexible dewcap (150 mm) can be fitted to tubes with an outer diameter of approximately 180 mm - 200 mm.
The dewcap has a seam marked space that can be cut out if the slipper of your searchlight tube gets in the way of attaching the dewcap. For binoculars where this is not necessary, the flexible dewcap can be made slightly narrower by fixing the Velcro 5 cm inside.
The Scopium flexible dewcap's black suede inner lining prevents light rays from the side from reaching your optics. The Scopium flexible dewcap will not only extend your valuable viewing time, it will also help you with its contrast enhancing effect.
Tip: Wrap the dewcap around your telescope tube to save space during transport.
