Milky Way and everlastings photographed in WA's annual wildflower season

The annual wildflower season is in bloom across regional Western Australia and photographers are hitting the road in search of the perfect shot.

Award-winning landscape astrophotographer Michael Goh said he had taken up to two years to get the perfect blend of night sky and blooms.

But he says a recent trip to Coalseam Conservation Reserve in the state's Midwest was a lucky mix of prior knowledge, a daytime scout of the area and a touch of technology.

"There was one particular night-sky time lapse involving everlastings which actually took me two years to capture … because the first year I was one or two weeks too late for the everlastings specifically," he said.

"So the next year I thought, 'I have to go back just a little bit earlier to catch them'.

"Because of course it depends on … rainfall and many other things … as to whether you'll actually get anything."

For his recent image showing the everlastings in the foreground and the Milky Way, he used a 2-minute shutter exposure to capture the night sky.

"It's a bit of a cheating one this one," he said.

"I actually have to confess, with this particular image … it is actually a bit of a blend of images because … I've actually taken the everlastings before it gets dark, then I take the other photo."

Mr Goh says the age and cost of equipment do not impede taking great photographs.

His cameras are between three and 12 years old.

"Nowadays with phones the way they are, you could actually, if you were patient enough, I'm very sure you could take a similar photo," he said.

Mr Goh said planning was key to getting a great photo.

He said you could only spot things you did not want in your photo, like rubbish bins, during daylight hours.

"I always believe in scouting first, so just wander around the park and look for interesting sorts of flowers or [if] you'd like to have a tree in the background.

"Unfortunately, you can't get one of the fantastic birds to sit still for an hour or so while you take a photo."

Mr Goh said knowing your own equipment through practice and trial and error was also important.

"I do a lot of experimenting ... and saying, 'Yeah, that's not going to work when I'm out on the field.'

"Knowing how to use your equipment is quite important."
