Baader Planetarium’s AstroSolar Safety Film delivers white light views of the Sun that are unmatched by any other objective solar filter or material. The views through AstroSolar display fine solar details, including fine penumbral detail, solar granulation, and lighter colored faculae. The disk is set against a dark background, free of the haze and scatter that is common in typical ‘mylar’ films or inexpensive glass filters.

The performance of AstroSolar is even more remarkable when considering its very low cost. Baader even has sizes large enough for producing full-aperture filters for very large telescopes . When combined with Baader’s tips for a simple do-it-yourself filter mount, anyone can construct a complete low cost – High Quality – white light solar filter for any telescope. It is possible to further improve the stability and sharpness of the solar image through the use of the Baader Solar Continuum Filter. Views of granulation and faculae are particularly enhanced through the use of this filter, in combination with AstroSolar. Users of achromatic refractors will be particularly pleased with the performance using this additional filter.

This highest precision film consistently produces strehl ratios of 94 to 96 percent in interferometric tests – thus it performs optically as well as a high quality Fluorite Triplet Lens by Carl Zeiss (per interferometric test results).

Baader even had a hard time themselves seeing any difference in performance between AstroSolar and 1/20 wave precision optical windows which they stocked from Zeiss. Their stock of precision polished plates runs into tens of thousands of dollars – all stocked for the 1999 eclipse – but AstroSolar was so good in fact, that these plates were hard to sell. Baader AstroSolar Safety Film shows notably more sharpness and contrast than any competitive objective filter we know of, especially including the affordable Glass Objective Filters and Mylar filters.

We have found that only our own superb Baader Herschel Safety Wedge is able to noticeably exceed the performance of AstroSolar. What is even more important – with AstroSolar the Sun appears in it’ s real colour – neutral white (with only a slight bluish tinge). Other films and glass filters produce a blurry bluish or reddish/orange/yellow 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”. Baader AstroSolar is essentially free from pinholes, since – unlike 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! No longer will solar observation be a “ho hum” experience, where you look into your telescope through an “economy priced” glass or mylar filter and wonder what this kind of amateur activity is all about.

Many of our customers have pushed out the glass or mylar from their older filters only to use their filter cell for AstroSolar – and experience a completely new, crisp, and incredibly aesthetic sun. All of a sudden, the telescope has the same performance during the day that it has at night, and now they realize that the consistently ‘poor seeing’ at their site was really just a consistently poor solar filter..

We are always amazed how easily some amateurs accept mediocre sharpness during observation of our nearest star, while they can be extremely critical if their telescope does not perform perfect on other stars (or planets). Not any more!
