AstroZap Baader Solar Telescope Filters


AstroZap Baader Solar Filter For 130mm and 155mm-165mm Telescopes AZ1013

Baader AstroSolar is unlike any other solar filter on the market! The sun appears in neutral white when using AstroSolar providing and exceptional observing experience. Other films and some glass filters produce blurry reddish or bluish Solar images which in turn cuts part of the spectrum. Faculae regions, which are visible mostly in the blue wing of the spectrum, are very hard to see with an orange sun. Because of the neutral color balance of AstroSolar, you can use various color (or interference) filters. This allows observers to focus on certain spectral passbands for investigations of different layers within the solar "atmosphere".

The uniqueness of Baader AstroSolar is not only in its ability to observe the sun using one of the best filters out there but also because of the dedication in making it one of the safest filters around. All processes in correlation to this product have been carefully tested and coatings are continuously inspected for consistency to ensure your eye safety. Further more, the National Bureau of Standards in Germany, the PTB has approved Baader AstroSolar for eye safety.

AstroSolar is essentially free from pinholes. Because of the coating on both sides, the probability of two pinholes overlapping each other is tremendously faint. There can be a time when pinholes do appear but to 1 out of 1000 only in optical density 2.5! Baader AstroSolar film Filter cell is constructed of lightweight 18Ga. aluminum and powder coated white. To ensure a secure fit, the Filter cell has heavy duty threaded inserts and nylon thumbscrews.
