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

Ez a segédeszköz kötelező azoknak akik szeretnék a váratlanul felbukkanó - eltűnő foltokat tanulmányozni, fáklyákat megpillantani a Nap pereméhez közeli területeken. (Nem protuberanciákat, azokat ez a fólia nem mutatja meg!) Ez a legjobb minőségű megoldás ugyanis a fóliák közt, és megérdemli hogy szerkesztünk hozzá megfelelő foglalatot ne csak befőttes gumival húzzuk rá a távcsőre. A távcső képet sem befolyásolja, legalábbis én nem vettem észre képromlást.
