Incredible smartphone photos showing Saturn passing behind the moon

On March 29, the planet Saturn and the Moon launched perfectly, which seem to move in the night sky. This relatively common, but easy to miss event is called a conjunction. And fortunately for his co-stars, astro photographer Grant Petersen managed to capture the business cycle using a smartphone mounted on a telescope. Petersen recorded the amazing image from above from Johannesburg, South Africa, then shared it into Twitter for the world to see. "It was terribly spectacular," Petersen said in the tweet accompanying his photo. "I smile from ear to ear, nothing will pick me up this astronomy high." The picture is actually a combination of several pictures, and it shows Saturn just before it slides behind the moon before dawn.

On March 29, the planet Saturn and the Moon launched perfectly, which seem to move in the night sky.

This relatively common, but easy to miss event is called a conjunction. And fortunately for his co-stars, astro photographer Grant Petersen managed to capture the business cycle using a smartphone mounted on a telescope.

Petersen recorded the amazing image from above from Johannesburg, South Africa, then shared it into Twitter for the world to see.

“It was terribly spectacular,” Petersen said in the tweet accompanying his photo. “I smile from ear to ear, nothing will pick me up this astronomy high.”

The picture is actually a combination of several pictures, and it shows Saturn just before it slides behind the moon before dawn.

Like many astrophotographers, Petersen said he constantly looks for “the next big astronomy event” that will be visible in his place. Sometimes the event is a passing comet or asteroid, other times it is the International Space Station zipping by.

To find out what’s coming, Petersen said he was using a lot of astronomy apps and diaries. The Saturn-moon conjunction came to his attention in January, and he was thinking of a plan to photograph it.

Petersen told Business Insider that he had “a lot of expectation and excitement that went on until the event” – that is, until rain came to Johannesburg the night before. But the bad weather cleared out to reveal a sharp net sky in time for the conjunction.

“When an event like this comes and everything goes according to plan, and [we] can avoid problems like weather, equipment failure or human error, it feels like a great achievement,” he said.

Petersen went up at 4 o’clock, or about two hours before the conjunction, to arrange and test his gear. His setup included an 8-inch dobsonian (a relatively inexpensive but large and powerful telescope), a Galaxy S8 smartphone, an adapter for connecting it to a lens and an eyepiece.

When Saturn lined up against the moon, Petersen played it in a video of 60 frames per second. After the economic cycle, he processed the images using a technique called stacking, which combines several images of lower quality into a brighter and clearer image. Then he shared his best photos with Twitter.

“I felt like a child at Christmas,” Petersen said. “I got a comment that said it reminded them of the first Earthrise image from the Apollo mission.”

Petersen also took the picture below, which shows how small Saturn looks when it is 950 million miles from Earth. The planet seems to be only a small part of the moon’s diameter, which in itself is small: about the width of your forefinger’s tip when held at the arm’s length against the night sky.

Petersen said the next big event he hopes to photograph is the Mercury transit over the sun on November 11.

“I’m really looking forward to that already,” he said.
