This SVBONY SV139 Telescope Moon Filter Kit helps reduce glare and enhance lunar detail when observing the moon through your telescope. Each filter is designed for specific moon phases to optimize viewing by reducing overall brightness.
* ND4 Filter (25% transmission): Ideal for Waxing Crescent Moon, allowing more detail to be seen as the illuminated portion grows.
* ND8 Filter (12.5% transmission): Best for Last Quarter and First Quarter Moon phases, providing clear views of half-illuminated lunar surfaces.
* ND16 Filter (6.25% transmission): Recommended for Gibbous Moon phases, reducing brightness as the illuminated part of the moon wanes.
* ND1000 Filter (0.10% transmission): Specifically for Full Moon observation, effectively reducing the intense brightness for detailed viewing.
