The 80mm AstroSolar ASTF Filter for 100-140mm O.D. Telescopes by Baader Planetarium:
About Baader AstroSolar Filters: Baader Solar Filters are designed to retain the real optical quality of the diffraction limited AstroSolar Safety Film in a precision mounted, temperature compensated cell. These professional quality Baader Solar Filters provide a secure and simple solution to observing and imaging the sun; utilizing AstroSolar Safety Film. Unlike most ready made filters- which stretch the filter material like a drum-head, destroying the image quality and rendering the film useless for any kind of high magnification work- AstroSolar works differently. By mounting the AstroSolar film in an entirely stress free fashion in a temperature compensated cell, it performs like a high-precision plane optical-window. Don't let ripples in the film fool you. By not stretching the film tightly, it is permitted to act as it should without any image distortion. To achieve this highly controlled filter construction, the film is firmly adhered to an injection-molded ring. The substrate of that centering ring has the same thermal expansion rate as the Baader film. To complete the construction, this carrier ring is free floating within an aluminum frame, held in place with an additional holding ring made of fiber reinforced plastic. This holding ring's job is to keep your filter safe from breakage. Baader SolarFilter ASTF filters are highly temperature stable, operating perfectly in temperatures between Neg.22-degrees F and 122-degrees F, nearly any observing conditions you might find yourself in.
Often H-alpha filters, which produce an image in a yellow-orange tone, are referred to as a natural colored image because we perceive the sun to be yellow and orange. In truth, Baader solar film produced a natural color view of the Sun - pure, white light with a slight blue tint. This permits visibility of the faculae regions of the Sun which are best seen in the blue portion of the visual spectrum. And because the Baader ASTF filters have total neutral color balance you can use a variety of color filters on the eyepiece to bring out further detail on the solar surface. The addition of a Baader Solar Continuum filter will further improve already excellent image stability and clarity. Faculae or bright spots on the sun are further enhanced with the use of a Continuum filter as well.
The end result is a white-light solar filter that exhibits no astigmatism during cold weather observing or on hot summer days, and is highly suitable for high magnification and detailed sun spot study.
Features:
AstroSolar film is delicate in nature. For this reason we cannot accept returns of this item once the box has been opened. Please measure your telescope carefully and when in doubt, give us a call or chat with us to make double sure the filter you're choosing will fit your telescope.
