Details:

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

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.

The views through astrosolar display fine solar details, including penumbra detail, granulation, and lighter colored facile. Securely packed in a cardboard box with stiff inlay for safely shipping the filter instruction booklet included.

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.

Solar filters made with astrosolar film a neutral density nd of 5. This still plastic ring is mounted onto the aluminum front frame.

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. A safety feature to absolutely ensure secure fit in front of the telescope under virtually all circumstances. Other films and glass filters produce a blurry bluish or reddish orange yellow solar image, thereby cutting part of the spectrum.

Outside diameter clamping range with included 20mm bolts: 120 - 150mm 4. Back to top 5. 0, cell mounted, and quality inspected by skilled members of Baader staff.

As a result, this filter is suitable for high magnifications and detailed observation of individual sunspots. Astf filters come with rubber plugs to be used as a cover for closing unused adjustment slots in the aluminum frame.

Important note: Scot users must only mount the filter to outside of tube limited depth front id prevents adequate engagement centering bolts. These bolts come in two diameters, 10mm and 20mm. However, this absolutely destroys the image quality, rendering film useless for high magnification work.

These are not included in the item price or shipping cost. Index scale provided beside each adjustment slot - adjacent to sliding fastener for fast and repeatable of the filter cell onto different telescope tubes.

Especially with an orange sun, it is very hard to see facile regions which are visible predominantly in the blue portion of spectrum. The film itself is cemented onto an injection molded ring, and substrate of that ring has same thermal expansion properties as astrosolar filter material. The thermal expansion coefficient of plastic and film are similar.

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

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.

Includes non-rotating sliding fasteners made from aluminum that hold the centering bolts. The performance of astro solar filter film is even more remarkable when considering its very low cost.

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

This can frequently take 4-6 weeks or more for several countries 8 Italy, Argentina, and south Africa Brazil. Views of granulation and facile are particularly enhanced through the use this continuum filter, in combination with astrosolar film.

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. This temperature compensated cell enables the astrosolar filter material to retain its excellent optical quality at any Nash be it 30 c or 50. Three security straps included to secure the position of filter cell with Velcro-adhesive pads.

Each bolt features injection molded rubber grip-faces, shaped to easily slide onto any telescope tube but hard come off.

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

Many ready-made filters stretch the filter material like a drum head in order to make it look piece of glass. 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 fastening system keeps the filter snugly in place and centers.

Back to top 4. For this reason the astf filter features a temperature compensated cell outside diameter clamping range with included 10mm bolts: 130 - 160mm 5. The astrosolar filter material is mounted onto a plastic ring where itself works as stabilizing element for cell.

Baader ASTF-100 astrosolar solar filter with temperature-compensated cell for all telescopes refactors, reflectors, 100mm 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 160mm 4. 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 . This can sometimes take 3-4 weeks to several countries.

This can often change from batch to according the whims of manufacturer.
