Crescent Moon & Mercury – 7th July 2024

A super collection of images by members of a Waxing Crescent Moon and Mercury taken on the 7th July 2024. The Moon had an illumination of 3%, which is the percentage of the moon that is illuminated by the Sun and an age of 1.6 days old, which is how many days it has been since the last New Moon.

Mercury is just above the 'M' on the label Mercury in the photo.

Image taken 6 hours after Honor and Jim's images in the UK.  Notice how the Moon position has changed relative to Mercury.

The Moon – 15th May 2024

A super image of the Moon taken by member Diane Clarke on the 15th May 2024. During this day the phase of the Moon is First Quarter.  The Moon is 49.91% illuminated; which is the percentage of the moon that is illuminated by the Sun. The Moon was 7.37 days old, which shows how many days it has been since the last New Moon.

Diane's image is a stacked image from a 10 min AVI file.  Taken with a Seestar s50, using Autostakkert, with slight colour correction using Affinity Photo.

You should also be able to make out the clair-obscur effects on the Moon known as the Lunar X and V in this image too. 

Lunar X and V are famous optical features on the Moon, visible for several hours around the time of the First Quarter through a telescope.  When the Moon’s terminator; the line between light and dark on the Moon is just in the right place, you can see a letter X and a letter V on the Moon’s surface.

Lunar X and V are examples of how lighting and topography can combine to produce a pattern that seems familiar to the human eye.  The X is formed when parts of the rims of the craters La Caille (68km wide), Blanchinus (68km) and Purbach (118km) catch the Sun’s light. The V is caused by Sun light illuminating the Moon close to the crater Ukert along with several smaller craters.

Crescent Moon

Two lovely images of a 32 hour old Moon with Earthshine taken by member Richard Bohner from Arizona on the 9th April 2024.

The 1st image of the crescent moon with Jupiter (top left) was taken with an iPhone.  The dot to the right of the Moon was an aeroplane.

The 2nd photo of the crescent moon was taken at 7:30 pm using a Canon 6D with 200mm telephoto lens f2.8, 1/20 sec exposure at ISO 3200.

The Worm Moon by Honor Wheeler

Three fantastic Full Moon images taken by CMHASD member Honor Wheeler on the 24th March 2024 from North Kent. 

This is the first Full Moon of the spring season and appeared on the night of Sunday 24th March and Monday 25th March reaching its peak illumination in the early hours of Monday 25th March 2024. 

In March, the Full Moon is also known as the Worm Moon and if it occurs on or after 21st March it is also known as the Paschal Moon, which is used to determine the date of Easter. In some years the Paschal Moon is the Worm Moon as in this year 2024; in others, it's the Pink Moon (Full Moon in April). The dates for the Paschal Moon range from the 21st March to the 18th April.

Honor used a Canon M6II, Tamron 18-400mm lens set to 400mm, F8.0, exp1/640s and ISO400.

Honor used a Canon M6II, Tamron 18-400mm lens set to 400mm, F8.0, exp1/640s and ISO400.


Full Moon and Blossom

The image below is a composite photo of the moon through an Apricot tree in bloom. The first photo was focused on the moon the second focused on the tree then overlayed using snapseed.

Honor used a Canon M6 II, Tamron 18-400mm lens and Tripod.
For the Moon exposure the settings were; lens set to 400mm,  F8.0, exp1/3200s and ISO800.

For the tree exposure the settings were; lens set to 400mm, F8.0, exp1.1/3sec and ISO800.

Lunar Clair-obscur Effects – French for “light” (clair) and “shadow” (obscur)

Some fantastic images showing two 'Clair-obscur' effects visible on the surface of the Moon taken by member Jim Burchell on the 19th & 20th January 2024.
Clair-obscur effects are revealed when light and shadow interact with the Moon's craters and other features to trick the eye into seeing something that isn’t really there.  Below are 7 of the best recognisable shapes created on the surface of the Moon.
Photo ref:
Most Clair-obscur effects require specific timing. Some last for days and are easy to see. Others last for a few hours and are more challenging.  Clair-obscur effects on the Moon are not one-time or rare events; this is because lunar lighting patterns repeat in a cycle of approximately 29.5 days, so each effect can be observed from somewhere on Earth once every month.
All of Jim's images below were a single shot; taken with a Pentax KP body attached to 102mm Altair Astro refractor. The images where then processed in Snapseed.
