  • ASTF: AstroSolar Telescope Filter
  • safe solar observation / photography with all high-quality telescopes and long focal length telephoto lenses
  • suitable for highest magnifications and detailed observation of sunspots etc.
  • AstroSolar Safety solar filter foil OD 5.0, mounted tension-free in temperature-compensating mount
    No astigmatic images in winter or with rapid temperature changes in summer

Baader Solar Filter - the standard
Mounted filters with Baader AstroSolar Safety Film OD 5.0
After more than 15 years of offering AstroSolar filter films as a do-it-yourself product, this new product family of Baader Solar Filters is designed to show the optical quality of AstroSolar Safety Film, which fulfills the condition of diffraction-limited quality.

Baader Solar Filters provide a safe way to observe and photograph the sun in the best possible quality using AstroSolar® Safety Film (OD 5.0). With many home-made filters, the filter material is stretched like a drumhead to make it look like a glass filter. However, this completely destroys the image quality and makes the filter unusable for higher magnifications. AstroSolar Safety Film must be mounted absolutely tension-free in order to act like a high-precision plane-polished optical window. This may seem contradictory to the usual perception of quality, but AstroSolar must show slight ripples. Only if the filter material is exposed to tension due to an inadequate mount, it will not work any better than a simple glass filter made of optically untreated window glass.

ASTF (AstroSolar Telescope Filter) Baader Solar Filter for high-end telescopes
This family of solar filters is particularly elaborately processed. AstroSolar film must not be exposed to any stresses either during assembly or due to temperature changes. For this reason, the ASTF filters have a temperature-compensating mount. The film itself is repeatedly glued to a frame made of injection-molded material, which has the same expansion coefficient as the filter material itself. This holding frame floats freely behind the aluminum frame and is held in place by another injection-molded ring made of glass fiber-reinforced plastic to eliminate any risk of breakage. This type of temperature compensation allows the AstroSolar filter film to maintain its excellent optical quality at any temperature, be it -30°C or +50°C.

All Baader Solar filters contain

  • Original Baader AstroSolar® Safety Film (OD 5.0), mounted and quality-tested by experienced employees of our company
  • pure white IR-reflecting front ring made of aluminum with stiffening edges along the outer and inner diameter, designed to protect the filter material from any contact with sharp metal edges
  • three centering pins with brass threaded insert are used to center the filter holder in front of the respective device opening. These pins have three different diameters, depending on the respective filter category (ASTF / ASSF / ASBF). Each of the pins has a ribbed rubber coating, which ensures that the filter can be placed easily over the telescopic opening, but makes it difficult for it to slip back into place
  • each of the centering pins can be attached without tools and allows adjustment to a wide range of tube diameters. The pins can be positioned on the outside or (if possible) also on the inside of the tube
  • Aluminum sliding blocks hold the centering pins. These sliding blocks do not rotate and have a milled pointer that points to a printed index scale
  • cross-head screws inserted in them allow the centering pins to be additionally tightened with a screwdriver if necessary
  • there is an index scale next to each punched adjustment opening for quick and repeatable centering of the filter for different tube diameters
  • a sliding, black locking plate covers the adjustment opening and prevents sunlight from entering the optics from the side past the filter opening
  • Only for ASTF filters: three rubber plugs serve as a closure to close the adjustment openings that are not required.
  • three safety straps with Velcro fastener and self-adhesive counterpart to secure the position of the filter in front of the telescope
  • the front of each filter bears the warning: Read the instructions before use
  • secure shipping carton

Scope of delivery: ASTF filters with apertures from 80 to 280mm include two sets of centering pins in 38mm length. 3 pins with 10mm diameter and 3 pins with 20mm diameter, adjustable for the respective diameter of the telescope tube or dew cap. Additionally 3 safety straps with self-adhesive pads, cover plugs for adjustment openings
