Astrozap AstroSolar solar filter, 136mm-146mm (45986)

AstroSolar™ film delivers 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 visibility of solar features such as faculae regions, which are most prominent in the blue part of the spectrum. Additionally, it allows the use of color or interference filters, enabling detailed observations of specific spectral bands and different layers within the Sun's atmosphere.

AstroSolar™ is coated on both sides, making it virtually free from pinholes and offering 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. This film has been rigorously tested for safety and approved by Germany's National Bureau of Standards (PTB). It is also CE-certified according to EG-Norm 89/686 and EN 169/92, ensuring consistent quality and eye safety. The filter cell is constructed from lightweight 18Ga aluminum, powder-coated white for durability, and includes heavy-duty threaded inserts and nylon thumbscrews for a secure fit.
