Corona, detailed view
80 eclipse images were taken during totality by means of a Canon EOS 5D digital camera equipped
with approx. 1 m focal length lens. Unfortunately a lot of images were influenced by clouds
and that is why the composition of all images in one resulting image was impossible. Finally 31 images
were chosen. About 550 other images (dark frames and flat-fields) were used for eclipse images
calibration. The resulting image shows not only the inner corona in the delicate details but
also the lunar surface is recorded in a quality not very far from an image taken during the
full moon. The position of the Moon represents the situation 139 seconds after the second contact,
i. e. 03:30:58 UT (15:30:58 local time).

Place | Enewetak Atoll, Marshall Islands |
Coordinate | 11° 21.546' N, 162° 20.827' E, 3 m altitude |
Conditions | Partially clear, partially small cumulus cloud, altitude of the Sun above the horizon 56-57° |
Optics | William Optics Megrez 88 Doublet FD + Baader Flat-field FFC, EFL 965mm |
Camera | Canon EOS 5D digital camera (ISO 100) |
Exposure | 1/125 s - 8 s |
Processing | Composition of 31 eclipse images. Eclipse images calibrated by means of dark frames and flat-fields, aligned by means of phase correlation, composed by means of LDIC 5.0 software, processed using Corona 4.1 in order to visualize coronal structures. Final processing was done using ACC 6.1 software. Image processing by Miloslav Druckmüller |
