Details:
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.
Technical:
The single image 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.
The sequence blends that mid-eclipse image with 6 others that are single 1/40-second exposures. The sequence progresses from the start of the umbral phase, at left, to the end, at right. The two images in between on either side of mid-eclipse were shot at roughly equal time intervals, to show the progress of the Moon along the edge of the umbral shadow.
All through the Askar APO120 refractor at f/7 with the Canon R5 at ISO 100. On the AP400 mount.
