Moon observation sessions with two amateur astronomers in Montargis

She’s used to it, she’s already said yes. On July 21, 1969, more than 500 million Earthlings were in front of their televisions to follow the first step of a man on it, the Moon. Since 2019, the French Astronomical Society has called for observational sessions to commemorate this historic event.. And also to find the excitement.

Crescent, full or gibbous, the internet is full of images of the Moon. But nothing beats the experience of Barbara De Brito and Guillaume Poulizac, amateur astronomers, who will make their observation equipment available to the public this Friday night in Montargis.

Three cities in the Loiret region stand out for their controlled urban lighting, which is conducive to biodiversity

The moon without a filter

The pictures on the internet are magnificent, but the idea during these sessions is to show the Moon differently. To observe it with your own eyes without a digital filter, ”explains Guillaume Poulizac, professor of physics and chemistry at Lycée Durzy.

“It’s a miracle the first time we see the Moon this way! It makes us think about our size compared to the enormous extent of the sky, with what lies elsewhere“, Barbara De Brito, a nurse and passionate about astronomy, abounds. Alongside her main activity, she has recently validated a university degree in astronomy at the Paris Observatory to satisfy her insatiable curiosity about the universe.

Snapshots from Earth

Aiming for the moon does not scare Guillaume and Barbara. Especially since they have adequate observation equipment. No small binoculars or toys galore. For one, a Dobson telescope for observing elements outside the solar system. For the other apochromatic telescope to distinguish the smallest crater from Earth’s natural satellite and take pictures of the deep sky (galaxies, nebulae, clusters).

The experience could be dizzying for some. Guillaume’s telescope is equipped with an equatorial mount, a small motor that allows flush with the earth’s axis of rotation and therefore to follow a star without having to change the angle of observation. While with one eye over Barbara’s telescope it will be possible to observe the motion of the earth.

Curious and amateurs will be able to admire the Moon from all angles and if they wish take pictures with the phone fixed on the lens. This is how Guillaume fell in love with astrophotography. He threw his head down into the stars of middle school with a school friend, taking his first pictures of space with the Dobsonian telescope of a high school friend. A passion that he today transfers to the high school students in the astronomy club who will come and practice handling the Schmidt-Cassegrain C8 telescope on loan from National Education as part of the “Astro at school” operation.

An association in sight?

On site, no scholarly presentation, but rather informal exchanges to answer the questions of the most curious. Barbara and Guillaume will shed light on the “scientific” aspect, but also on “star mythology”. They can also count on the presence of members of the Astro Club in Ouzouer-sur-Loire.

Finally, the two friends also hope to create their own union. Note for lovers of the cosmos … The new Guardians of the Galaxy may be in Montargis.

Practice

Curious and amateurs are expected between 18.00 and 22.00. See you Friday night in front of the post office in Montargis, Saturday night at the Lac des Closiers near the skate park and Sunday night in front of the Alticiné. Free entertainment.
