On March 29, planet Saturn and the moon lined up perfectly, seeming to touch in the night sky.
This relatively common yet easy-to-miss event is called a conjunction. And luckily for his fellow earthlings, astrophotographer Grant Petersen managed to capture the conjunction using a smartphone mounted to a telescope."That was frickin spectacular," Petersen said in the tweet accompanying his photo. "I'm smiling from ear to ear, nothing gonna get me off this astronomy high."
The image is actually a combination of several photos, and it shows Saturn just before it slipped behind the moon before dawn.Grant Petersen, an astrophotographer in South Africa, uses a telescope, adapters, and a smartphone to take detailed photos of the night sky.
Petersen told Business Insider that he had "a lot of anticipation and excitement running up to the event" - that is, until rain hit Johannesburg the evening before. Luckily, the poor weather passed to reveal a crystal-clear night sky in time for the conjunction.
"When an event like this comes along and all goes according to plan, and [we] can avoid issues like weather, equipment failure, or human error, it feels like a great accomplishment," he said.
Petersen got up at 4 a.m., about two hours before the conjunction, to arrange and test his gear. His setup included an 8-inch dobsonian (a relatively cheap and portable yet large telescope), a Galaxy S8 smartphone, an adapter to connect it to a lens, and an eyepiece.As Saturn edged toward the moon, Petersen recorded it in 60-frame-per-second video. Then after the conjunction, he processed the images using a technique called stacking to merge several of the video frames into a brighter, clearer picture. Then he shared his best photos to Twitter.
"I felt like a kid at Christmas," Petersen said. "I got a comment that said it reminded them of the first Earthrise pic from the Apollo missions."
Petersen also took the photo below, which shows how small Saturn looks when it's 950 million miles away from Earth. The planet appears to be just a tiny fraction of the moon's diameter, which itself is small: about the width of your index finger's tip when held at arm's length against the night sky.An occultation of Saturn and the moon, as seen from South Africa on March 29, 2019, using a smartphone mounted to a telescope.
Petersen said the next big event he hopes to photograph is the transit of Mercury across the sun on November 11.
"I am really looking forward to that already," he said.Copyright © 2021. Times Internet Limited. All rights reserved.For reprint rights. Times Syndication Service.
