Once you've seen one, you'll want to see more.
That is the view of many eclipse chasers, who travel the world to catch a glimpse of the rarest of solar spectacles.
For husband and wife Marcelo and Isabel Domingues that includes travelling from their home city of Brasilia, in Brazil, to the remote West Australian town of Exmouth, about 15,000 kilometres away, to witness this month's total solar eclipse.
"For the eclipse chasers, the eclipses provide an opportunity to know different countries that you might not normally visit," Mr Domingues said.
"Seven years ago, I went to an event in Iceland to see the total eclipse, and in 2016 we went to Indonesia.
"I think everyone needs to see one total eclipse one time in their lifetime because it's a magnificent event in the sky, and if you experience one you probably want to see more."
Seasoned eclipse chaser
Up to 25,000 stargazers from all over the world are expected to travel to Exmouth to see the total solar eclipse on April 20.
For Queenslander Kate Russo this will be her 13th eclipse.
"I've been on mountain tops, I've been in deserts, I've been in a boat in the middle of the ocean, 800 miles west of the Galapagos Islands," she said.
"I've seen eclipses from pretty much all continents, apart from Antarctica.
"There are very limited options in Australia; if you're wanting to see this eclipse on land, you really just have to go to that very small area."
Fellow travellers
Ms Russo said the eclipse-chasing community had grown over the years.
"It used to be quite a very niche area and sometimes people would just see you as quite geeky, and they didn't really get it," she said.
"Now I think it's become mainstream, so there's more and more people who want to see it."
She said while most people will enjoy seeing a total solar eclipse not everyone will become an eclipse chaser.
"As a psychologist, I'm really interested in that," she said.
"I'm just curious about why some people, like me, will stop anything and everything to get into the path [of totality], whereas others will enjoy it and think it's amazing and special, but they don't have that same level of drive and determination.
"There will be a proportion of people who are coming to see this eclipse in April who will then want to see the next one, and the next one and the next one, and then that's the chaser community."
First-timer intrigue
Sally Cunningham and her husband Andy didn't consider taking in the eclipse when they started their caravan trip across to Exmouth from Victoria.
"Initially, it wasn't a big thing, because we were just really keen to catch up with our friend," Ms Cunningham said.
"Now we're getting swept along in the excitement."
They've allowed five weeks for the journey to make time for stops along the way.
"We're just going along and meeting lots of new people," she said.
"We found everyone's been particularly friendly, and very interested when we tell them that we're going up for the eclipse."
