• AstroSolar® ECO-size Safety Film 5.0 for solar observation and photography at high magnification
• Size: ca. 140 x 155 mm, incl. DIY-instructions and DIY cutting-template – telescope quality – Optical Density (OD) = 5.0
• Safe for visual solar observation (with additional optics) and imaging
• 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
• 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.
• The film is from the same material as our proven AstroSolar® Safety Filme 5.0 in A4-size, due to high demand now availble in a smaller size at an economical price, suitable as solar filter for small telescopes, finders, binoculars, spotting scopes and camera lenses

The L-Pro Astrophotography CCD filter is a filter for improving the contrast of deep-sky objects and dampening the sky background.

• blocks UV and IR (700 - 1100 nm)
• high transmission at passband
• improved color balance for DSLRs and One-Shot Color Astro Cameras, e.g. ASI Color Cameras cooled or uncooled by ZWO.
• high optical quality
• in 1.25" filter cell
• The L-Pro Nebula filter permits roughly 3x longer exposure times than without a filter and therefore improves contrast significantly.

The L-Pro CCD filter improves the contrast of deep-sky objects and reduces the sky background.
