#PPOD: Saturn is captured here by NASA's Cassini spacecraft. Cassini orbited the gas giant for thirteen years before ending its mission by plunging into the planet's atmosphere on September 15, 2017. This image is a mosaic compiled from frames recorded by Cassini two days before its final dive. 🧪 🔭

My Celestron EdgeHD 8" SCT is for capturing planetary, lunar, and deep space objects such as galaxies, star clusters, and planetary nebulae. When capturing large nebulae, I use my refractor telescope.

Saturn is the 6th planet in our solar system, famed for it's spectacular ring system.
As the rings are inclined to the plane of Saturn's orbit, we see them at different angles through the years. Here we see the change from 2019 (L) to 2025 (R). #astronomy

In 1668 Isaac Newton built the first reflecting telescope, inspired by his prism experiments on light and colour; he solved the chromatic blur in glass lenses. Using Cassini and Flamsteed’s observations of Jupiter’s moons (1687), he proved his law of universal gravitation held true. #AstroHistory

Cassini’s long-focus refractors, built by Campani, were mounted at the Paris Observatory and on the “Marly Tower.” He used them to study Jupiter’s moons and their eclipses—data later key to Römer’s discovery later that the speed of light is not infinite as was the view at the time #Astronomy

In 1665, Giovanni Cassini was first to observe a “Permanent Spot” on Jupiter, though probably wasn't today’s Red Spot using 34-ft refractors at the Paris Observatory. He tracked it for years to measure Jupiter’s rotation. Cassini’s drawings survive in Paris Observatory archives. #AstroHistory
