Details:

The filter comes with two sets of 3 injection molded centering-bolts length 38mm threaded brass inserts to filter-cell in front tube opening.

This can often change from batch to according the whims of manufacturer. Each bolt features injection molded rubber grip-faces, shaped to easily slide onto any telescope tube but hard come off.

These bolts come in two diameters, 10mm and 20mm.

The disk is set against a dark background, free of haze and scatter that common in typical 'Mylar' films or inexpensive glass filters. Three security straps included to secure the position of filter cell with Velcro-adhesive pads. Ideally, astrosolar film must not be put under stress, either during mounting of the or any temperature change.

This can sometimes take 3-4 weeks to several countries.

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.

Other films and glass filters produce a blurry bluish or reddish orange yellow solar image, thereby cutting part of the spectrum. Index scale provided beside each adjustment slot - adjacent to sliding fastener for fast and repeatable of the filter cell onto different telescope tubes.

This still plastic ring is mounted onto the aluminum front frame. The astrosolar filter material is mounted onto a plastic ring where itself works as stabilizing element for cell astf filters come with rubber plugs to be used cover closing unused adjustment slots in aluminum frame.

Solar filters made with astrosolar film a neutral density nd of 5.

However, this absolutely destroys the image quality, rendering film useless for high magnification work.

Many ready-made filters stretch the filter material like a drum head in order to make it look piece of glass. Important note: Scot users must only mount the filter to outside of tube limited depth front id prevents adequate engagement centering bolts. Bolts are made to contact the outside of optical instrument tube for most applications. Even though it may seem counter intuitive, Baader astrosolar film must show slight ripples.

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. Baader ASTF-200 astrosolar solar filter with temperature-compensated cell for all telescopes refactors, reflectors, 200mm aperture suitable high resolution, magnification applications over a wide range of temperature conditions includes mounting accessories centering bolts, sliding washers, fasteners, and safety straps can be attached to items an outside diameter not 260mm used visual photographic, imaging video.

This temperature compensated cell enables the astrosolar filter material to retain its excellent optical quality at any Nash be it 30 c or 50.

The views through astrosolar display fine solar details, including penumbra detail, granulation, and lighter colored facile. The thermal expansion coefficient of plastic and film are similar.

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

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

These are not included in the item price or shipping cost inside diameter clamping range with 10mm bolts: 250 - 280mm 9. It is also possible to further improve the stability and sharpness of solar image through use Baader continuum filter sold separately.

Outside diameter clamping range with included 20mm bolts: 220 - 250mm 8. Especially with an orange sun, it is very hard to see facile regions which are visible predominantly in the blue portion of spectrum inside diameter clamping range included 20mm bolts: 260 - 290mm ASTF-200 solar filter specifications item number: or astrosolar film aperture: 200mm 7.

This can frequently take 4-6 weeks or more for several countries 8 Italy, Argentina, and south Africa Brazil.

0, cell mounted, and quality inspected by skilled members of Baader staff. 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.

The film itself is cemented onto an injection molded ring, and substrate of that ring has same thermal expansion properties as astrosolar filter material. 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.

As a result, this filter is suitable for high magnifications and detailed observation of individual sunspots.

This fastening system keeps the filter snugly in place and centers. Suited for aperture range: 190 - 210mm 7. 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 .

Astrosolar safety film delivers white light views of the sun that are unmatched by any other objective solar filter or material.
