Features:
The moon filter installation size is 1.25 \". Both sides have universal 1.25 \" threaded interfaces, which can be connected to all 1.25 \" telescope eyepieces and other telescope adapters.
The moon filter's optical glass only allows 13% of the incident light to pass through, which increases contrast and can distinguish the details of the moon, which is very suitable for small telescopes.
It can prevent moon glare and reduce brightness, allowing us to see more moon features, such as ravines, mountains, and valleys.
Not only does it help you see more surface features and details, but the moon filter can be used in combination with other filters, allowing you to learn them more conveniently.
When the moon is full, it will produce dazzling light. It is recommended that you use the moon filter to achieve the best possible viewing quality.
