While surfing the other night, I discovered a shareware astronomy program
that shows the stars within 9,000 ly of our sun, as well as numerous deep-
sky objects across the galaxy, in 3-D. It allows you to travel to any star or
other object, and also has a galaxy view that shows our local neighborhood
in the perspective of the galactic arms. The program is called "Sky3D", and
I found it at Cnet Online, http://www.cnet.com. Once there, go to the
"Downloads" area, and in the search window there, type "sky3d", w/o
quotes, and it will take you to the download link.
This an MS-DOS program, and navigates a bit oddly but really shows a
good perspective of where we are in the galactic scheme.
P.S. I am still looking for information regarding translating between star
catalogs. If I have an SAO designation for a star, and I have only the
Hipparcos and Tycho catalogs, is there a way to get from one to the other?
Any online star catalogs?
