K&F ND filter
Variable ND filter, 2 filter discs that when rotated polarize the passage of light from dim to dark. In equatorial and/or alt azimuthal mount together with a Vastar adapter, they allow photography sessions of sunrise and/or sunset. The 72mm filter allows you to protect all the cell phone's photography sensors from incident light from the Sun, but it is also advisable to make homemade adaptations to protect the cell phone completely as shown in the photographs.
