Four timesteps from the final 7 seconds before #Venus vanished behind a distant roof structure today: each image 1/3.2 second at f/2.8 and ISO 400 with maximum digital zoom yielding an equivalent focal length of abou 3 meters, pictures in full resolution and cropped, no further processing. The spectral #dispersion is clearly visible; unfortunately Venus 'hit' the structure from the side, so cutting off the red and leaving only the green/blue upper part as in #AtmosphericalOptics

A lot of #AtmosphericalOptics seen from a ferry in the Baltic Sea between Lolland and Fehmarn Friday which was engulfed by fog while the Sun was high: a Brocken spectre, a glory and a fogbow! The spectre was particulary impressive to the eye as it was both colorful and 3D, a kind of tunnel vision effect.
