Eclipse 2024 – Totality and Partial Phases over Lac Brome, Quebec
Eclipse 2024-Totality and Partial Phases over Lac Brome (April 8, 2024).jpg
This is the sequence of the total eclipse of the Sun over the waters of Lac Brome, in the Eastern Townships of Quebec, Canada, on April 8, 2024. Onto the base single exposure of the totally eclipsed Sun set in the darkened eclipse sky I have layered in images of the pre- and post-totality partial phases taken every 5 minutes from the start to the end of the eclipse. As the Sun moved across the sky from left to right, the Moon moved across the disk of the Sun from right to left.
The twilight sky colours are from the light of the Sun from areas outside the path of totality. This is looking southwest, the direction toward the eclipsed Sun but (to the right) also the direction the lunar shadow arrived from and where the sky brightened first at the end of totality.
This was from the Tiffany Park area of Lac Brome in the Eastern Townships of Quebec, on the east side of the lake where several dozen cars and eclipse chasers gathered this day for a fine view. The bright object below the eclipsed Sun is Venus. High cirrus clouds added to the sky colouration and visibility of the shadow passage.
The base image was taken near mid-eclipse. It is a single 1/6s-exposure from a 1200-frame time-lapse, with the Canon RF15-35mm lens at f/2.8 and Canon Ra at ISO 125. Sky detail and contrast emphasized with Luminar Neo Enhance filters.
The partial phase images, however, are greatly reduced close-ups taken through a telescope, the Astro-Physics Traveler 105mm refractor, and through a Baader solar filter. They were shot at 610mm focal length and all 1/800 second (except 1/400 for the thinnest phases) at ISO 100 with a Canon R5.
I have resized and placed the partial phases to be fairly accurate to their actual position, eclipse phase, and motion of the Sun across the sky over the roughly 2.5 hours of the eclipse from first to last contact. So these were not taken with the same lens and camera as the main totality image. But it is representative of the actual scene.
