Details:
Here comes a bit more sophisticated image of the solar corona during a recent hybrid eclipse. The image taken from Pebble Beach, Australia, is the result of deeper bracketing work, including 61 different exposures from 3 cameras (all on 1m telephoto lenses) and calibration data. The orientation of the image is not exactly north-south (to preserve the full field of view). You can notice several bright prominecnes, which were visible even to the naked eyes during the 1-minute-long total solar eclipse as the Moon as it reflected the Earthshine. The image shows the moment of the diamond ring phenomenon when the epic eclipse ends. Used two 1100mm tepehoto lenses wit Canon 6D cameras and one 1400mm telephoto lens with Canon 6D Mark II, all on two on Vixen GP-2 mounts. Two identic 1100mm sets produced 30 exposures (from 1/500 to 4s), total 60 exposures, the 1400mm only 1/500s shot of detailed prominences. Darkframes, and flat fields were applied.
You can also enjoy a short 4K timelapse view to the total solar eclipse on 20 April 2023, taken from Pebble Beach of Exmouth, Western Australia. You can notice several bright and large prominences seen during the 1-minute-long totality with some slight changes during the phenomenon. Timelapse is created from a quick sequence of 1/500s exposures with 1400mm telephoto lens (ISO 100, tracked on a mount) and Canon 6D Mark II. Video here -->https://www.youtube.com/watch?v=0OsIYr45rvM
