The moon's orbit around the Earth is slightly elliptical. As a result, the distance between the moon and Earth varies throughout the month and the year and thus the apparent size of the moon changes. But by how much? The composite shows the moon in both extremes. The moon image on the left was photographed on April 7, 2020 (moon at perigee), the image on the right was photographed on September 13, 2019 (moon at apogee). Quite a difference... Images taken through an 8-inch f/5 ONTC Newtonian reflector. 1.15x TeleVue Paracorr coma corrector & Nikon D7500 (h alpha modified).
