The OFIL-BP-ASOLV-080 filter is coated with Baader's patented BP (Broadband Polarization) technology. This technology filters out the majority of the sun's dangerous infrared and ultraviolet light, while also reducing the intensity of harmful polarized light. This results in a filtered view of the sun that is both safe and visually appealing, with a natural color that closely resembles the sun's true appearance.

The filter is designed to fit a wide range of telescopes and binoculars, making it a versatile addition to any solar observing setup. The 203mm square shape allows for easy alignment with the eyepiece, and the filter can be securely attached to the telescope using a holder or adaptor (sold separately).

The Baader AstroSolar OFIL-BP-ASOLV-080 filter is made from high-quality optical glass, ensuring sharp and clear images. The filter is also scratch-resistant and has a durable coating that protects it from the elements. The 0.8mm thickness of the filter provides adequate protection against solar flares and other solar events, making it a reliable choice for solar observation.

In summary, the Baader AstroSolar OFIL-BP-ASOLV-080 filter is a high-quality, versatile, and safe solar filter that is perfect for any solar observing enthusiast. Its BP technology provides a natural color view of the sun, while its scratch-resistant coating and durable construction ensure long-lasting performance. With its 203mm square shape and ability to fit a wide range of telescopes and binoculars, this filter is a must-have for any solar observing setup.

Details:

Views of granulation and facile are particularly enhanced through the use this continuum filter, in combination with astrosolar film.

It is also possible to further improve the stability and sharpness of solar image through use Baader continuum filter sold separately. Check the cleaning result by holding cleaned filter up to sun.

In most cases, an unobstructed filter size of 3-4 inches diameter should be sufficient. Will combine the shipping weights and show you discounted cost.

The optical and mechanical properties of film are not compromised.

This can often change from batch to according the whims of manufacturer. The performance of astrosolar is even more remarkable when considering its very low cost.

The film is manufactured by Baader Planetarium, Germany.

Use careful, gentle strokes.

Its reflective property reduces intensity of sunlight by over 99. When combined with Baader tips for a simple do-it-yourself filter mount see below, anyone can construct complete low cost, high quality, white light solar any telescope, binoculars, or camera lenses. Back to top 5.

Due to its absolute homogeneity, the foil attains optical performance of high quality plane-parallel glass filters. Baader sells their astrosolar safety film in just three sizes a4 or. The views through astrosolar film display fine solar details, including penumbra detail in sunspots, granulation, and lighter colored facile.

Putting it right against a very bright light will show mottled and non-uniform appearance, but again, this is normal does not indicate problem with the film piece. Please also note that the flashlight test is not a good way of inspecting this film. This implies that the filter film will block 99. Astrosolar safety film provides white light views of the sun that are unmatched by any other front-mounted solar filter or material.

The basic development of this precision film was made in laboratories for nuclear and particle physics. This is because pinholes act as diffuse sources of light, not point. Baader astrosolar safety film has been approved for eye by the national bureau of standards in Germany, OTB.

A simple google search for solar filters will show you dozens of sites with examples other amateur astronomers have made, along some excellent photos the sun shot this filter material. Baader astrosolar safety film - 8 x 203mm square piece.

The solar disk is set against a dark background, free of haze and scatter that common in typical 'Mylar' films or inexpensive glass filters. Sometimes, it also appear that the film might be slightly warped. Especially with an orange sun, it is very hard to see facile regions which are visible predominantly in the blue portion of light spectrum.

Fingerprints on the metalled surface are to be avoided under all circumstances.

Unlike any other solar filter on the market, astrosolar is ce-tested according to egg-norm and en notified body this absolutely normal natural, it does not imply that film defective. For each stroke, a new portion of cotton should be used, soaked with the cleaning solution.

The sun appears in its real color - neutral white not blue or orange.

Since the coating is harder than regular aluminum coatings applied on mirror surfaces, it can be cleaned with a solution of dishwater detergent and distilled water.

On the flip side, a smaller aperture provides steadier images when seeing conditions are turbulent, which is most often case in places. Other films and glass filters produce a blurry bluish or reddish orange yellow solar image, thereby cutting part of the spectrum. One layer of this foil is sufficient for the construction a safe, high resolution solar filter.

All processes connected to this product have been thoroughly tested. Tiny pinholes can be covered with a black felt-tip marker.

The base material is not cheap Mylar. 5, 3/4 6 7 and 8 square pieces.

4 sheet, medium 19. 4 roll, and extra large 46x46 roll.

Appearance of Baader astrosolar filmed first glance, film appears to be like a thinner version ordinary aluminum foil. If scratches or pinholes show up, exceeding a combined un coated area of 10 square mm, the film is regarded as unsafe and must be destroyed. Hence, the chance of two pinholes overlapping each other is extremely small. Larger filters also provide higher contrast, resolution since you are using a aperture, the theoretical resolving power is, and more comfortable to use get exit pupil when conditions good.

Obtain sterilized cotton wool as used for eye application, available in pharmacies. High density coatings on both sides of the foil ensure a highly uniform filtering capacity without pinhole effect, resulting in an extremely contrast solar image with neutral characteristics.

012mm thick. Normal cotton wool as used for cosmetic purposes should not be. You can construct a full aperture filter or smaller off-axis for your telescope.

Coatings are inspected constantly for consistency to ensure your eye safety.

Eye safety astrosolar film is essentially free from pinholes since, unlike even the most expensive glass filters, it coated on both sides. Back to top 3.

The quality of solar image is immeasurably better than can be achieved by using so-called Mylar rescue blankets or similar materials. Back to top 4. If the filter becomes very dirty, we encourage you to replace it, rather than risk damage in cleaning process.

Baader astrosolar film filters must be mounted in the front of telescope.
