CAA member Frank Shoemaker, despite challenging seeing conditions and the early hour, captured a fine image of the September 14 conjunction of Earth’s Moon and planet Venus. As luck would have it, the conjunction occurred in constellation Cancer home of the lovely open cluster M44, the “Beehive”. The technical info.: Canon EOS 6D Mark 2, 100mm, f/4.5, 19 seconds, 5:29 a.m. Eastern Daylight Time.
Penumbral lunar eclipses — when the Moon passes through the thin outer shadow Earth casts into space — are not spectacular. We described the July 4 – 5, 2020 eclipse as “subtle” when we wrote about it in advance. It turned out to be not-even-subtle. Essentially nobody could tell whether an eclipse had even happened, even in photographs tortured to bring out shadow details. Announcing penumbral eclipses is tricky: if nothing is said about them before they happen, we get asked why; if we promote the eclipse and even say it may be slight, people get disappointed when they hardly see the effects or don’t see anything happen at all. Still, we got to talk about the geometry of eclipses and people looked at our beautiful Moon, and that’s something.
CAA member and accomplished photographer Alan Studt took advantage of the brilliant Moon to make its portrait. Studt explained this photo of the Moon is a composite, made up of images recorded at the peak of the eclipse. “Never saw a shadow,” he wrote, “which was fine with me.”
Alan Studt made his picture from two different shots/exposures: One shot for the clouds & one shot for the Moon. The clouds, Saturn, Jupiter and its moons (look closely at Jupiter) were all in one shot, 180mm, f/5. Just the Moon & clouds shot were 550mm, f6.3 Sky: 1/13th sec., ISO 5000. Moon: 1/125th sec., ISO 80. The images were post-processed in Lightroom & layer blended in Photoshop.
Let’s hope for clear skies the evening of June 30 when the ongoing conjunction of Jupiter and Venus gets really cozy! Tuesday evening will see the two planets sharing a space only 1/3-degree apart in our sky; they will look like a brilliant double star. After Tuesday’s encounter, the planets will drift slowly apart night-by-night but will remain a beautiful sight in twilight. Chart courtesy Sky & Telescope – www.skyandtelescope.com
Despite the fact it was 9 degrees (F) and just before 11:00 PM, I simply had to go out and try a shot of the Monday night (January 21) close conjunction of the Moon and Jupiter. Skies had cleared and the day’s occasional snows stopped, so I had a good opportunity. I stepped out on to our sidewalk and, tolerating the frigid breeze as long as I could, shot several exposures, bracketing the shutter speed. I only got one or two that were acceptable to me mostly due to focus being off. The image I’m sharing is sharp enough that (in the uncompressed original) even shows hints of Jupiter’s cloud belts, diagonal here in its tiny disk. None of Jove’s moons show due to the short exposure needed to record Earth’s Moon, just hours away from apogee. Pictures done and shared, it was off to slumberland having witnessed a cold celestial dance before bed. — James Guilford
