Sunrise partial solar eclipse sequence composite

From my location in Mississauga, Ontario, Canada the June 10th, 2021 partial solar eclipse was in progress at sunrise, reaching maximum visible coverage of about 70% at 5:40 AM, just as the Sun fully cleared the horizon. Due to clouds my first image in this sequence at the lower left is at 5:50 AM, about 10 minutes after maximum partial eclipse. The last image at the upper right is from 6:39 AM, at the end of the eclipse, where the sun is still less than 10 degrees above the horizon.

Images were taken with a Canon 70D using as a filter, consisting of half of a pair of solar viewer "Suncatcher" glasses. The cardboard frame on the one side of the glasses was trimmed to fit, then held in place under a UV filter on my zoom lens, which was at 250 mm. The "Suncatcher" filter is metallized mylar, and so is quite neutral in color.

Photos were at f/9, varying from about 1/50 s initially to 1/400 s at the end, mostly at ISO 3200, except the first images were at ISO=6400. All images were handheld, the camera braced on the railing of the bridge I was on. I am glad I did not try to use a tripod as it was very windy.

In the images the first images are much redder than the later ones due to the closeness to the horizon as well as the clouds, which are also clearly visible. Changes in the color are due to changes in the altitude and clouds and haze. The sequence from bottom left to top right is arranged in this composite to match a Stellarium simulation of the eclipse, except that the size of the lunar/solar disk is 2X larger, to fill more of the final composite image.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
