Neutral density filters reduce
excess light by a certain
percentage without modifying the
color of the image (neutral). We will use them for lunar and solar observation, especially in those phases with a higher
% of light or brightness .
We remember that for solar observation you always have to supplement with a
specific filter for solar observation , but at risk our sight.
Neutral filters have different
% density , from
0.6% to 3%, they adapt from lesser to greater degree to less or brighter observations.
Among the filters with adaptation to
2 "diameter , we offer the following possibilities:
- DN 0.6% with 25% light transmission
- DN 0.9% with 12.5% light transmission
- DN 1.8% with 1.5% light transmission
- DN 3% with 0.1% light transmission
