Baader 7,5 nm Solar Continuum 2" Filter (540nm). Never use any eyepiece filter for solar observation without objective front filter!

More about the product

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

Fotografikus észlelésnél nagymértékben megkönnyíti a napfoltok finom részleteinek, és a granuláció apró struktúráinak megörökítését. A rögzített nyersanyag kontrasztján sokat javít, egy-egy jobban sikerült egyedi képkocka, már önmagában kiváltja a \"húha\" érzést. Használatával a légköri nyugodtság az 5 fokozatú nappali seeing skálán kb. egy fokozatot javul.

Cons

Csak egy célpont esetén tudjuk bevetni, az ára más alternatíva híján és talán a speciális bevetési terület miatt meglehetősen borsos. Nekem a távcsővel látott vizuálisan kép e szűrő nélküli jobban tetszik, de ez nagyon-nagyon egyénfüggő. Fotografikus észlelés során a keskeny áteresztési tartomány miatt az expozíciós idő növekedésével kell számolnunk.

Summary

Aki szeretné a maximumot kihozni a napfoltok, és a granuláció észlelésénél, annak ajánlott kiegészítő. Az igazi tudását csak jó minőségű herschel prizmával párosítva tudjuk kiaknázni.
