Svbony IR Pass 2" SV183 685 nm is a professional infrared filter for astrophotography, especially useful when photographing the Moon and planetary astrophotography.

The use of this filter allows you to obtain the effect of obscuring the background in planetary astrophotography, which allows you to take high-contrast and detailed shots just after dusk or just before dawn.

This filter can also be used in nature photography, where thanks to the high permeability to the near infrared it is possible to show many details of clouds or plants.
