The current solar maximum cycle will continue to peak throughout 2024 offering sunspots that will change and morph from one day to the next. Many people viewed the sun for the first time during the April 8th eclipse and were wowed by the level of activity. We encourage you to continue popping your scope out during the day to observe or photograph the progression of sunspots across the surface of our dynamic sun.

If you don’t have a solar filter for your scope or binoculars yet, consider making one with AS50A4 or AS50HM AstroSolar filter material or purchase a pre-made filter made by Baader Planetarium or Kendrick Astro.

AstroSolar® Safety Film, Optical Density 5.0, is the ideal material for visual solar filters. Baader Planetarium developed this safety film in anticipation of the 1999 solar eclipse in Europe and it remains unsurpassed for safety and visual quality to this day.

When using AstroSolar® Safety Film 5.0 – mounted in front of your optics – you can image the Sun and safely look through the viewfinder of your camera – or you can directly look into the Sun with telescopes and binoculars at any suitable magnification. The diffraction-limited performance ensures that your image quality remains excellent so that you can discern fine surface details of the sun.

The coating of AstroSolar® Safety Film 5.0 is subject to constant quality control. Its reflective property and security for solar observation through optical instruments is being tested repeatedly.

AstroSolar® Safety Film 5.0 reduces the intensity of solar radiation by 99,999% to a factor of 1 : 100 000 of the initial value. Multiple coating processes on both sides of the carrier film are adding up during production to result in a perfectly uniform filtering result and help in neutralizing the effect of microscopic pores in the coating hat plague conventional glass solar filters which are commonly only coated on one side of the glass.

Important note: AstroSolar® Safety Film 5.0 is NOT authorized to be used for naked eye solar observation or production of solar viewers. Look for solar eclipse glasses that comply with the ISO 12312-2:2015 standard for naked eye solar viewers
