Description
Why you need to choose Svbony SV139 moon filter
1. SV139 moon filter is more professional than others, as it is designed for four different moon shapes. This can give you a better viewing experience.
2. Unlike other filters, the moon turns green. The SV139 moon filter retains the actual colour of the image so that the moon remains white but only less bright.
3. SVBONY SV139 moon filter reduces the transmission of light refractor light and offers you more details you can observe, such as craters and cracks on the moon surface.
25% transmission filter - growing crescent moon
As the moon moves around the earth, we see more and more of the light half and we say the moon grows. This phase is called the crescent moon. It is very good to use the 25% transmission filter at this time.
