Alpine Astronomical ASOLV-S overview

  • 1Description

Specifically designed for photographing and viewing the sun and solar eclipses through an optical device such as telescopes, binoculars, or camera lenses, this 7.9x11.8" sheet of Baader AstroSolar White-Light Safety Film 5.0 from Alpine Astronomical filters the sun's intense light to a safe level and blocks harmful ultraviolet (UV) and infrared (IR) radiation. Viewing through the film reveals solar surface details including penumbral detail, solar granulation, and lighter-colored faculae. The film improves sharpness and contrast while showing the sun in its proper white color, instead of the orange/red or blue tint common with broad-band filters which filter a portion of the visible spectrum and inhibit observing fine details. Also, since the entire spectrum is being passed through, the use of secondary filters is possible to selectively observe specific bands or highlight targeted solar features.

Use of this filter is intended only for the front apertures of telescopes, binoculars, spotting scopes, and camera lenses, and shouldn't be used without an optic for direct solar observation. Learn how to fabricate custom filter mounts at the manufacturer website.

    Alpine Astronomical ASOLV-S reviews

    Baader AstroSolar White-Light Safety Film 5.0 (Small A4 Sheet) is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from It's great, but very flimzy I bot this to expand my telescope use to daytime and in anticipation for the next full eclipse. Since I got large-ish 9.25" celestron, I could have bought the larger 12x12 but I saw no need to let in more light into the telescope with it being big enough as it is and also saved some money. I also made my own holder from stiff cardboard. The film itself is very finicky to work with, very thin yet surprisingly hard to cut (meaning you could easily rip across it while cutting!!!) and must not be touched with bare hands, must not be stretched, must not be creased, must not must not must not....... But overall it worked well and I'm happy with the filter. I was concerned that it doesn't change the sun color to orange but that turns out to be a good thing and you can see the sun in its normal color. Also note: this filter will NOT allow you to see the sun prominences and flares. For that you'd need the expensive hydrogen alpha (HA) filter.
