Tuesday/ the Great Conjunction of Saturn and Jupiter

Galileo started to turn his telescope to the heavens in 1609.
He soon discovered Jupiter’s four biggest moons, and that Saturn had a ‘strange oval surrounding’. Right around that time, there was the Great Conjunction of 1623 – but it is almost certain that Galileo did not see it.
Astronomers and historians have not found the event mentioned anywhere in the records of that time.

Check out this incredible picture posted on Sunday night by J. Rehling on Twitter (@JRehling). 

In his Twitter thread notes below, he says that he used a 9.25″ (that means wide) Celestron telescope with a 2350 mm focal length and an ASI 1600 mm monochrome camera, with separate filters for clear, red, green, and blue.

And when is the next super-close pairing of the two planets? March 15, 2080.
