1018 meters per meter
a light year (ly)
a parsec (pc)
8 solar systems
distance to Local Bubble wall
~~2500 to ~~3000 Pm
"complete dust depletion"
Star size is very false (actually... star is ~atom and solar system is ~blood cell).

Basically, BD is ~5cm towards you, Sun/Barnard's/Wolf are ~on the screen, and the others are ~3cm behind it.
There are some stereo pairs here, which might make it easier, though the orientation and names are different :(.

starmap: Figure out orientation.
Ideally would have galactic orientation (this is celestial?),
some depth cue (perhaps a galactic plane grid),
cross-hairs rather than icons (to avoid false size cuing),
Pm rather than pc distances.
sketch of local stars, ly and pc.
clarify dimensions, describe egg shape
describe dust and gas densities
more about local neighborhood
Limit of reliable distance info (Hipparcos?) 100 pc? Reliable means what?
landmarks: ltyr=10^16, pc=3ltyr,
"Some ?? systems total." in ^17 and ^18 frames.
Make size of local bubble image and box a bit less sloppy.
Quote from pillar cloud caption, regarding erosion process. Neat.
Cloud pillar slightly (50%?!) too big I think...!! Drat.
Starmap was contributed by Winchell Chung and resized slightly.
Sketch of local bubble derived from The 120 pc Map: the Local Bubble
in 3-D Mapping of [LIM].
The sizes of this ~3000 Pm cropped image, and of the ~1000 Pm red box,
are very rough, having been done very quick and sloppy.

Pillar clouds from here (Hubble).
Size of image is not quite correct - tallest pillar is about a ly long.
I am uneasy about using false-color images - one's grip on reality is
