Welcome to the Astronomical Society of Kansas City

The purpose of the Astronomical Society of Kansas City (ASKC) is to provide a
community to support education and outreach to the Greater Kansas City area,
observing events and research opportunities for members and guests, and
resources for all interested in astronomy and allied sciences.

Since the 1920s, the ASKC has grown from a small group to one of the largest
astronomical societies in the country, with well over 500 members. Although
there are a few professional astronomers among us, most members are
amateur astronomers from widely diverse backgrounds with a unifying
interest in observing and discovering more about our universe.

Solar Safety Film

Baader Planetarium AstroSolar® Safety Film

AstroSolar^® Safety Film 5.0 for solar observation and photography at high magnification, telescope quality, Optical Density (OD) = 5.0.
Best suited for precision work with all astronomical telescopes and binoculars – just as well as for all photographic camera- and tele-lenses.
This highest precision film consistently produces strehl ratios of 94 to 96 percent at interferometric tests – thus it performs optically like a Fluorite Triplet Lens by Carl Zeiss or Astro Physics
Safe for visual solar observation only under these conditions:

Must be used in conjunction with a telescope or binocular.
Must be placed in front of the objective lens or mirror - NEVER between the instrument and the eye.
Not safe for direct solar viewing.
Does not comply with ISO 12312-2.

Great for imaging.
- Does not deteriorate the transmitted wavefront.
For more than 25 years on the market, the only film-material made to not deteriorate the optical wavefront, it does allow to attain high magnification with any long-range optics without reducing sharpness or contrast of the solar surface.
