DescriptionBecause of the light reflecting off the rocky surface, we can see the moon at night. When observing the moon through a telescope, the bright reflected light will produce obvious glare. In order to easily increase contrast and reduce glare, we recommend using a telescope moon filter.Features- Color: Yellow - Material: Aluminum alloy, Optical glass - Size: About 3.00X3.00X1.10cm/ 1.18X1.18X0.43inch- The filter is designed for moon observation. Don't look at the sun with this filter. - Ultra-thin filter to minimize vignetting. There is no deviation due to temperature changes during use. - Making for more comfortable lunar views exhibiting higher contrast.- The Moon is one of the most interesting objects in the night sky to observe through a telescope.- A must-have astronomy accessory, suitable for both beginner or professionals to use.
