AstroZap Baader Solar Telescope Filters Size - Meade ETX80
- Made with Baader AstroSolar™ 18Ga. film Filter cell
- Aluminum, powder-coated frame with double coated film

Baader AstroSolar™ film Filter cell constructed from lightweight 18Ga. aluminum and powder coated white. Heavy duty threaded inserts and nylon thumbscrews insure a secure fit.
With AstroSolar™ the Sun appears in neutral white. Other films and some glass filters produce a blurry bluish or reddish Solar image, thereby cutting part of the spectrum. Especially with an orange sun, it is very hard to see faculae regions which are visible predominantly in the blue wing of the spectrum.
Due to it's neutral color balance, AstroSolar enables the use of various color (or interference) filters which allows the observer to concentrate on certain spectral passbands for investigations of different layers within the solar "atmosphere".
Eye safety
AstroSolar™ is essentially free from pinholes, since - other than with even the most expensive glass filters - it is coated on both sides, so that the chance of two pinholes overlapping each other is extremely faint. Pinholes do appear, but to 1 out of 10000 only in optical density 2.5! Baader AstroSolar™ safety film has been approved for eye safety by the National Bureau of Standards in Germany, the PTB. Unlike any other Solar Filter on the market, AstroSolar™ is CE-tested according to EG-Norm 89/686 and EN 169/92 ( notified body 0196). All processes connected to this product have been thoroughly tested. Coatings are inspected constantly for consistency to ensure your eye safety!

1.25" Orion Hydrogen-Beta Eyepiece Filter
- Orion's Hydrogen-Beat eyepiece filter makes it possible to view the elusive Horsehead, California, and Cocoon Nebulas in dark skies
- Selective band-pass filter transmits only the hydrogen-beta light these faint nebulas emit
- Filter allows you to observe targets that are considered trophies of visual astronomy
- Best used with a moderate to large aperture telescope and clear, dark skies
- Threaded to fit 1.25" eyepieces and threaded diagonal barrels
Our Hydrogen-Beta Filter may be the only way to see the faint and elusive Horsehead, California, and Cocoon Nebulas. It blocks everything but the hydrogen-beta light these faint nebulas emit, providing the contrast needed for viewing. By isolating the hydrogen-beta spectral line centered at 486.1 nm in a 12nm band-pass and blocking other wavelengths, it effectively blackens the background sky, allowing the faint nebula to become clearly defined. It increases contrast even under dark skies so you can visually capture these prized targets. Use with a moderate to large aperture telescope under clear, dark viewing conditions. Threaded to fit 1.25" and 2" eyepieces and diagonals.
