Total lunar eclipse September 2025

A total lunar eclipse occurred in the wee hours of 8 September 2025. It was supposed to peak at 0311 local time. (Note: All photographs taken with a Canon EOS 550D, focal length 400mm, aperture f/6.3, ISO 400)
 
At 0104, the moon was still bright. (exposure 1/500s)
 
By 0129, the moon has started to "disappear". (exposure 1/500s)
 
0159, moon about half gone. (exposure 1/500s)
 
0214, starting to turn red. (exposure 1/500s)
(exposure 1s)
 
0232, the moon has more or less entered total lunar eclipse. (exposure 2s)
 
0248, really red now. (exposure 2s)
 
0311, peak. (exposure 2s)
 
0331, getting really sleepy so I took a last photo and did not wait for the moon to exit earth's shadow. (exposure 2s)

During total eclipse, I took more photographs at 5s exposure. However, without a proper star mount, the photos turned out a bit blur. But it was easier to appreciate the redness of the lunar eclipse in those photos with 5s exposure. For example, this was taken at 0311 with 5s exposure.
 
The last time I photographed a total eclipse was in 2022, when it occurred with Uranus lunar occultation.
