The Planet Saturn at Opposition
July 14, 2020
(Click on Picture for larger view)
The earth was directly between the sun and Saturn on July 21, 2020 and I was able to get a few images from the 11" Celestron EdgeHD telescope using a 2x Barlow resulting in a focal ratio of f/20 (which enlarges the view). At that time, Saturn was 837,761,600 miles from earth. There are numerous moons around Saturn with 53 confirmed and named with another 29 awaiting confirmation. However, only a few can be seen in the image I took including the large moon Titan.
Titan is the largest moon of Saturn and the second-largest natural satellite in the Solar System. It is the only moon known to have a dense atmosphere, and the only known body in space, other than Earth, where clear evidence of stable bodies of surface liquid has been found. Titan is larger than the planet Mercury but a bit smaller than the largest moon in the solar system, that being Ganymede which orbits Jupiter. To capture an image of the moons, I greatly over-exposed the planet then after cutting out the over-exposed planet, I pasted the image of moons over a normal exposed view of Saturn.
