New Digistar projector will whisk planetarium audiences all over the solar system and around the universe

Call it one giant leap for the planetarium at the Manitoba Museum.

From the outside, the domed theatre on Main Street looks the way it has always looked since it was constructed 44 years ago.

The fate of "Marvin"

Marvin is still a presence at the planetarium, silhouetted like a dumbbell-shaped sentinel in the theatre's centre, as he has done for almost half a century.

"Marvin" is the nickname given to the Zeiss Mark Vs projector that was state of the art when it was installed in 1968.

"It's still impeccable at showing the sky as seen from earth, so we're still going to use Marvin," says planetarium honcho Scott Young. "He's still fully functional.

"But what we're finding though is because of the sheer versatility of the Digistar, the stars look pretty darn good and that means that we'll be using Marvin less than we thought we would.

"But he's our mascot. He's our icon. One day we'll be talking about how Marvin has been retired out to the science gallery where people can see him as an artifact rather than a planetarium projector. But we're a few years away from that."

But on the inside, the theatre has undergone a radical upgrade after closing to the public on Sept. 4.

As every conventional movie theatre in town has converted from film to digital projection, the planetarium has gone digital with a new $381,700 projection system called the Digistar 5.

To outward appearances, that means a couple of small box-like video projectors have been added to the base of the existing old-fashioned projector.

But the upgrade gives planetarium staff the impressive power to whisk audiences all over the solar system and around the universe.

Scott Young, astronomer and manager of science communications at the Manitoba Museum, offered an early demonstration of the new system's capabilities, piloting a high speed trip to Saturn, where the audience can seem to travel through the rings of the sixth planet from the sun for an up-close look at the debris floating in its orbit.

"The Digistar system has three computers in the back that basically process all the star data and the planet's positions," he says.

"It's not just digital projection, it's digital calculation. We're actually calculating the universe in 3-D in real time.

"It's like having the universe in a box that we can fly around in and play around with. So you can literally go anywhere and do anything and update things as they occur."

"Something could be discovered and announced by the astronomical authorities and we can literally cut and paste it into the show right then. Digistar just adds it to the list of the hundreds of thousands of things it's already calculating and just puts it right up there."

The upgrade also allows the planetarium to present special shows that weren't available on the old Zeiss projection system.

"That's a big driver," Young says. "Most of the people who are creating shows now are using the latest technology so they weren't supporting older theatres like we had. We were having a hard time finding good content. But now we can basically choose from the best shows being produced in the world in any format."

But Young is especially excited about the chance to create new shows with Digistar's capability of roaming the universe.

"We've never been able to present shows the way they look in our heads because the technology wasn't there," he says. "Now we don't have that limit. Now, the cool stuff we come up with goes right out to the audience.

"It's the way things should be. We're just thrilled."
