Projection of the Moon

You have certainly already observed a solar eclipse in projection; that is, the telescope was pointed at the Sun and its light was projected onto a white sheet or sheet.

Personally, I had never done this for the Moon before; at least I hadn’t given enough time to it.

That evening, a few hours before the Full Moon of February 16, 2022, I decided to point the famous 62cm telescope of the Saint-Véran observatory at the Moon and I put a 100mm eyepiece there. 🌔

The telescope, with a focal length of 9 meters, then benefited from a 90x zoom. This allowed me to have the entire Moon.

A little patience to achieve the development of the projection on the wooden board and we obtain a 70cm Moon on the wooden board.
