Details:

This fastening system keeps the filter snugly in place and centers. Astrosolar safety film delivers white light views of the sun that are unmatched by any other objective solar filter or material. This can often change from batch to according the whims of manufacturer.

Bolts are made to contact the outside of optical instrument tube for most applications.

However, this requires a clear depth of about 20mm on the inside for adequate engagement centering bolts which many instruments like binoculars, camera lenses, and Scot Mack-cads telescopes do not have.

Outside diameter clamping range with included 20mm bolts: 200 - 230mm 7. As a result, this filter is suitable for high magnifications and detailed observation of individual sunspots. The filter comes with two sets of 3 injection molded centering-bolts length 38mm threaded brass inserts to filter-cell in front tube opening.

Other films and glass filters produce a blurry bluish or reddish orange yellow solar image, thereby cutting part of the spectrum. These bolts come in two diameters, 10mm and 20mm. Ideally, astrosolar film must not be put under stress, either during mounting of the or any temperature change.

This family of solar filters is made in the most elaborate way, and its construction design superior to that astf ass line Baader.

It is also possible to further improve the stability and sharpness of solar image through use Baader continuum filter sold separately.

The disk is set against a dark background, free of haze and scatter that common in typical 'Mylar' films or inexpensive glass filters. Astf filters come with rubber plugs to be used as a cover for closing unused adjustment slots in the aluminum frame.

Includes two sets of 3 injection molded centering-bolts with threaded brass inserts to the filter-cell in front tube opening 10mm and 20mm diameter 38mm length .

The performance of astro solar filter film is even more remarkable when considering its very low cost. This can frequently take 4-6 weeks or more for several countries 8 Italy, Argentina, and south Africa Brazil.

Even though it may seem counter intuitive, Baader astrosolar film must show slight ripples.

These are not included in the item price or shipping cost.

This temperature compensated cell enables the astrosolar filter material to retain its excellent optical quality at any Nash be it 30 c or 50 f back top The views through astrosolar display fine solar details, including penumbra detail, granulation, and lighter colored facile. Their innovative design and construction enables each filter to fit a wide range of instruments - from high end telescopes, spotting scopes, camera lenses, even special versions binoculars.

Important note: Scot users must only mount the filter to outside of tube limited depth front id prevents adequate engagement centering bolts. Views of granulation and facile are particularly enhanced through the use this continuum filter, in combination with astrosolar film.

Solar filters made with astrosolar film a neutral density nd of 5. Can be used for visual and photographic, imaging video applications.

For this reason the astf filter features a temperature compensated cell. A safety feature to absolutely ensure secure fit in front of the telescope under virtually all circumstances.

Especially with an orange sun, it is very hard to see facile regions which are visible predominantly in the blue portion of spectrum.

Back to top The thermal expansion coefficient of plastic and film are similar. This can sometimes take 3-4 weeks to several countries.

This still plastic ring is mounted onto the aluminum front frame.

Black sliding washers supplied to securely cover the full length of adjustment slots in aluminum frame Nash for blocking sunlight from passing trough filter cell beside area. Astrosolar is mounted entirely stress free onto Baader filters in order to perform like a high precision plane-optical window.

Each bolt features injection molded rubber grip-faces, shaped to easily slide onto any telescope tube but hard come off. Clear white Ir-rejecting front ring with reinforcing raised edges along the outer and inner circumference, designed to protect solar filter material from contact any sharp metal edge. Securely packed in a cardboard box with stiff inlay for safely shipping the filter instruction booklet included. Astf-180 solar filter specifications item number: or astrosolar film aperture: 180mm 7.

Suited for aperture range: 170 - 190mm 6.

The astrosolar filter material is mounted onto a plastic ring where itself works as stabilizing element for cell. The film itself is cemented onto an injection molded ring, and substrate of that ring has same thermal expansion properties as astrosolar filter material.
