Sky & Telescope - April 2023 - 63

OUT OF THE SHADOWS Long exposures
reveal details on the lunar disk
often overwhelmed by the beauty (and
brightness) of the corona during a total
solar eclipse. This image is a single
2½-second exposure recorded through
a 90-mm Vixen refractor during the July
2, 2019 eclipse from Vicuña, Chile.
SOLAR CHEMISTRY An array of bright emission lines in
the solar atmosphere is revealed in the flash spectrum
visible far from the solar limb at the final moments of
totality as seen from Las Flores, Argentina, on July 2,
2019. The picture was recorded with a Nikon D800 DSLR
camera and 300-mm lens fitted with a diffraction grating.
