Astrozap AstroSolar solar filter, 259mm-269mm (45988)

AstroSolar™ film offers a neutral white view of the Sun, unlike other filters that produce bluish or reddish images, which can obscure parts of the solar spectrum. This neutral color balance enhances the visibility of solar features, such as faculae regions, which are most prominent in the blue part of the spectrum. It also supports the use of color or interference filters, allowing observers to focus on specific spectral bands for detailed studies of different layers within the Sun's atmosphere.

AstroSolar™ is coated on both sides, making it virtually free from pinholes and providing superior optical quality compared to even high-end glass filters. The chance of overlapping pinholes is extremely low, occurring only in 1 out of 10,000 cases in optical density 2.5. Tested rigorously for safety, it has been approved by Germany's National Bureau of Standards (PTB) and is CE-certified according to EG-Norm 89/686 and EN 169/92. Its coatings are consistently inspected to ensure reliability and eye safety. The filter cell is constructed from lightweight 18Ga aluminum, powder-coated white for durability, and features heavy-duty threaded inserts and nylon thumbscrews to ensure a secure fit.
