Partial Lunar Eclipse (Sept. 17, 2024).jpg

This is the minor partial eclipse of the Moon of September 17, 2024, taken at mid-eclipse when only 8% of the lunar disk was immersed in the Earth's umbral shadow, taking a dark bite out of the northern edge of the Full Moon. This is not enough of an eclipse to show any reddening of the umbral shadow as at a total eclipse or even a major partial eclipse.

The rest of the Moon was within the lighter penumbral shadow, creating the gradient of brightness across the disk with the southern region brighter than the north.

The Moon was low in the southeast, and so yellowed somewhat by atmospheric absorption of the blue wavelengths. One lone star shows up above the Moon, 5th magnitude 20 Piscium. The Moon was in Pisces for this eclipse.

Technical:
This is a blend of two exposures: a short 1/40-second exposure for the main disk and a longer 1/10-second exposure taken immediately after, to bring out the area at top in the umbral shadow. Both through the Askar APO120 refractor at f/7 with the Canon R5 at ISO 100. On the AP400 mount.
