Description

This was a fun event to image, even if the eclipse itself was underwhelming. I was told there would be 98% coverage, so I definitely expected more shadow than what I saw, but maximum eclipse was only 45 minutes after local Moonrise, so being stuck nearer to the horizon undoubtedly complicated any clear view of the shadowed Moon (which is why this image starts about 17 minutes after that).

The weather was beautiful - in a shocking turn of events, Kansas winter turned to 60F during the day with little wind, and during the night it was in the high 50s F, quite pleasant as compared to the last few all-nighters imaging in the freezing cold. I enjoy this hobby considerably more when I don't have to worry about keeping the feeling in my toes.

Image sets were taken every 15 minutes starting at 6:45pm (2 minutes after maximum eclipse), as earlier attempts had been foiled by clouds. Each set contained 50 subs, and for each set the exposure was adjusted to ensure the histogram on all images stayed relatively close to the others, varying between 1/1000" and 1/500" depending on local cloud cover and increasing brightness of the Moon as it exited our shadow.

I had a lot of math prepared for this regarding how the eclipse magnitude relates to the exposure time at a given ISO but was quite a ways off - my expected 1/90" exposures for maximum eclipse translated to 1/500" in reality, but estimating magnitude by eye can be difficult since there is little opportunity to practice. Still, this was a greatly appreciated opportunity to practice for the upcoming Solar Eclipse over North America.

Images were then batch edited in Photoshop (edit one while recording an action set, then apply it to all other images) to increase Saturation and correct color since they were fairly yellow, being lower on the horizon than I normally image. One final image of the Moon at 9pm local time was added in the hope that any remaining shadow on the Moon at 8:30pm (23 minutes before the end of the eclipse) would be easier to see.
