Baader 7,5 nm Solar Continuum 1¼" Filter (540nm). Never use any eyepiece filter for solar observation without objective front filter!

WARNING! For visual observing, the Continuum filter has to be used together with a Baader AstroSolar Photographic (ND 3.8) film filter and an ND0.6 neutral density filter! 

The Continuum filter is not the proper tool to observe H-alpha active regions, but helps a lot to see granulation and the fine structures inside sunspots. Available in 1.25" and 2" size.

  • A must for owners of achromatic refractors. This filter cuts the spectral range transmitting a specific spectral range around 540nm, completely cutting out blue and red wavelengths in an area of the lens system that where the optics are at their sharpest.
  • Enhances contrast and reduces the effect of atmospheric turbulence.
  • This filter must be used in conjunction with a Baader Herschel Wedge or Baader AstroSolar Safety Film for solar observations otherwise eye or equipment damage may occur.
  • Planeoptically polished, non-ageing sealed coating edges.

Pros

Döbbenetesen kontrasztos képet ad a Napról, a zöld képe kellemes a szemnek

Cons

Elég húzós az ára!

Summary

A szűrő hatékonyan növeli meg a napfelszín részleteinek kontrasztját, segítségével sokkal határozottabban látszik a granuláció, a foltok belső szerkezete és a fáklyamezőket is kiemeli. Én Herschel-prizmával használom, az ND3 szűrő mellett alkalmazandó további neutrál, vagy polárszűrő helyett. A Nap képe ZÖLD színben jelenik meg benne, ami első pillantásra szokatlan, de a szemnek nagyon kellemes, \"itatja magát\" a látvány. Fényképezéshez is kiváló, az ND3 szűrővel együtt is ISO200-nál 1/3200s expozíciós időt lehet használni általában. Az ára miatt sokat gondolkodtam a vásárláson, de most már tudom, hogy megéri az árát. Mivel a zöld fény egy vékony hullámhossztartományában enged át, ezért csillagtesztre is használható.

Drága. Ha valaki vizuális napfóliával használná, akkor sok fényt elvesz.
