Lunar Eclipse
Partial Lunar Eclipse of 17 September 2024
Description
On September 17, 2024, a partial eclipse of the moon occured, with only 3.5% of the lunar disk cast into shadow by the Earth's umbra. I initially intended to see the eclipse from Washington DC, but it was forecast to be cloudy that night. Unfortunatly, everywhere else within a 3 hour driving radius was also forecast to be cloudy, so I was tempted to sit this eclipse out. However, I saw that there would be some breaks in the low clouds in eastern Pennsylvania around the time of maximum eclipse, so I decided to give it a shot. I drove 3 hours to Hazleton, PA, and set up my camera around 10:20 PM eastern time, right when the eclipse began its partial phases.
It was still very cloudy, so the shots I got were quite blurry. However, I was able to reveal some of the moon's surface features using Photoshop. First, I took the clearest image I took with the least amount of clouds, and I put that as my base layer. I adjusted the dehaze, clarity, and texture sliders. I then took a long exposure, and after adjusting those same sliders, put a high-pass filter on it, and set the blend mode to "overlay." I stacked 3 identical high pass filters on 3 separate layers, which gave me a pretty good image. However, the top of the lunar disk, which was eclipsed, was still too dark to be shown. I then took a longer exposure than the previous two, and masked the bottom away, so the only thing visible was the top eclipsed portion. I again adjusted some sliders, and ran 3 high pass filters with an "overlay" blend mode. I cleaned up some dust specks on the image that came from my camera sensor, and then I was done.
