Benjamin Knispel<p>Very nice pollen based atmospheric optics.</p><p>Last night I observed a pollen corona around the bright moon. These colored rings around the moon are created when its light is refracted by airborne pollen.</p><p>Depending on the type of pollen, different ring shapes and sizes appear. This one is probably from pine pollen.</p><p>Image: 22:53 CEST | f=300 mm | aperture 5.6 | ISO 1250 | 0.5 s</p><p><a href="https://chaos.social/tags/AtmosphericOptics" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>AtmosphericOptics</span></a> <a href="https://chaos.social/tags/Photography" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Photography</span></a> <a href="https://chaos.social/tags/Nature" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Nature</span></a> <a href="https://chaos.social/tags/Light" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Light</span></a> <a href="https://chaos.social/tags/Diffraction" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Diffraction</span></a> <a href="https://chaos.social/tags/Moon" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Moon</span></a></p>
