I really enjoyed the lunar eclipse earlier this week, my gear worked without any errors and the skies were very clear. I'm almost 30 and this was the first time that I visually observed a lunar eclipse. The next one visible from Western Europe only occurs in 2029, so I'm glad that it all worked out this time.
Looking through the eyepiece, I could easily observe both the illuminated and eclipsed parts of the Moon simultaneously. But the difference in brightness was actually huge (over 9 photographic stops) and it was impossible to capture the dynamic range of the entire scene with a single exposure. Nonetheless, I tried to recreate the visual appearance of the event by combining several different exposures into HDR images. Blending the layers involved quite a bit of artistic freedom, it's mostly my own memory of the event.
The HDR images seem to have a bit more depth or 3D-effect due to the rounded shape of Earth's shadow. I quite like that, because the shadow was one of the first things that blew me away during the observation.
