Photographer captures a ‘once-in-a-lifetime image’ of astronauts spacewalking outside the ISS

German astronomer and photographer, Sebastian Voltmer, recently accomplished a most impressive feat: capturing astronauts on a spacewalk outside the International Space Station, from the comfort of planet Earth, using nothing more than an off-the-shelf telescope.

About the

This image was snapped on March 23rd, 2022 using a C11 EdgeHD telescope, “shortly after sunset in the bright evening sky over Germany,” says Voltmer. And clearly shows astronauts Matthias Maurer and Raja Chari performing a routine spacewalk outside the station—Chari is the seemingly dangling upside down.

“I feel like I just made a once-in-a-lifetime image. It’s probably the first ground-based showing two spacewalkers on the ISS at the same time,” Voltmer says.

About the telescope used

The C11 EdgeHD telescope, used by Voltmer, can be purchased new for around $4,500 on its own (or closer to $6,500 with mounting accessories). While that isn’t exactly cheap, it’s also not outside the realm of attainable for an avid astrophotographer—and hey, it’s more affordable than the Dragonfly Telephoto Array, made from 168 Canon 400mm lenses.

The telescope has 2800mm of reach and a fixed f/10 aperture. No word yet on what camera Voltmer mounted to the C11 to make this shot. But we’ve reached out to him for confirmation and will update the article when we know more.

The wrap

This once again proves that you don’t need to be a professional photographer to capture something amazing or unique. And even if you don’t have a pricy telescope (or camera), you should still get out there and explore! Who knows, maybe you’ll shoot a once-in-a-lifetime photo too.
