More about the product

The Baader solar filter is available in two different type: ND5 is for visual observations and ND3.8 for photographic work. The filter consist of energy rejection coating on both sides which practically does not distort the image (according to specification the distortion is below 4%). According to our tests it is recommended to use an ND0.6 neutral density filter (or ND0.9 above 15cm) which helps to observe the granulation at 100-120x magnification. The filter does not change the Sun's natural color.

Pros

It's a neutral density filter and therefore gives a natural, true color of the Sun - white, and also permits imaging beyond light spectrum. With lower optical density it permits very fast lucky imaging.
