The film itself is cemented onto an injection molded ring, and substrate of that ring has same thermal expansion properties as astrosolar filter material. Back to top 5.

Bolts are made to contact the outside of optical instrument tube for most applications. Securely packed in a cardboard box with stiff inlay for safely shipping the filter instruction booklet included.

Includes non-rotating sliding fasteners made from aluminum that hold the centering bolts.

The astrosolar filter material is mounted onto a plastic ring where itself works as stabilizing element for cell. Three security straps included to secure the position of filter cell with Velcro-adhesive pads.

Important note: Scot users must only mount the filter to outside of tube limited depth front id prevents adequate engagement centering bolts. 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 inside diameter clamping range with included 20mm bolts: 340 - 370mm can frequently take 4-6 weeks more for several countries 8 Italy, Argentina, and south Africa Brazil. The disk is set against a dark background, free of haze and scatter that common in typical 'Mylar' films or inexpensive glass filters.

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

A safety feature to absolutely ensure secure fit in front of the telescope under virtually all circumstances.

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

Suited for aperture range: 270 - 290mm this reason the astf filter features a temperature compensated cell. Other films and glass filters produce a blurry bluish or reddish orange yellow solar image, thereby cutting part of the spectrum. The views through astrosolar display fine solar details, including penumbra detail, granulation, and lighter colored facile.

Ideally, astrosolar film must not be put under stress, either during mounting of the or any temperature change.

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 can often change from batch to according whims manufacturer.

These bolts come in two diameters, 10mm and 20mm. The thermal expansion coefficient of plastic and film are similar.

Astrosolar is mounted entirely stress free onto Baader filters in order to perform like a high precision plane-optical window.

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