"Sounds straightforward." She steps out of the bridge to avoid distracting or annoying the crew flying the ship.
"Create a perfect sphere of black around me. This should be a long gray smudge, brighter in the center," she whispers, making a line just above the sphere's equator, going nearly all the way around. That will be the backdrop of the galaxy. "White dots here, here, here..." She points to a number of stars in a 'y' shape, just above the galaxy line. "With this one being larger. Make this one smaller, and slightly redder. Hmm, no, move this one slightly..." she pulls the spot of white over a few inches.
"Add an information tag to this dot, saying 'farther away but a large star'. And this one gets a tag saying 'third closest star to us, a small star. Has two gas giants.' Add a tag to this section, saying 'the way these stars are parallaxed by our movement means the shape looks like it's slowly closing its top two branches as we pass.'"
More dots are added. She knows more information about what (unsuitable for life) planets are around the closest handfull stars than exactly how they look, so a lot of the information is contained in floating text. The star at their destination, decades away at the speed the fleet is travelling, gets a paragraph. One of it's planets is the right distance and size to be terraformed into a livable world. A few of the closer stars she doesn't know where they are, only their descriptions, which go into a seperate set of text notes tacked onto the sphere's dark top.
She takes a minute to try and think of anything else, but has run out of things to add. "Save this thing as-is but shrink it and move it into my hand," she whispers to it at last, then goes to carry it back to the captain.
