By purchasing the adapter set, the compatibility of the Pard NV007 can be increased, since the product only comes with a 45 mm adapter as a factory accessory, which means it can be stably attached to eyepieces with a diameter of 45 mm. The adapter set can be used well if the viewing side diameters are between 36 mm and 48 mm. The adapter can be adjusted to size using the various additional rings. In practice, it works like a sprinkler hose extension clamp. The clamped wedge profile ring can be clamped to the appropriate diameter with the thread of the adapter.
