See also: How to use the Constellation Java Applet
Take a look at some of the other Java programs I have written.
This is a program that allows you to look at the constellations as they appear on the sky. It allows you to scroll around and zoom in or out. It is still pretty new (I started it on 8/21/96) so it can't do a whole lot yet.
The "New" constellations were created by H.A. Rey (the author of Curious George) about 40 or 50 years ago. The Standard constellations came from XEphem version 2.8 (they were created by Chris Marriott and translated by Elwood Downey).
I know it's really slow. My apologies for that. I will try to speed it up soon.
I got the idea from StarGazer by tasanan@smart.net. Try it. It's very good.

| Fixed problem with interrupted redrawing of sky. Now there are no more errors with (1) incorrect colors and (2) misdrawn stars/constellations. |
| Allowed relative URLs for he data files instead of absolute ones pointing to www.astro.wisc.edu. This will help portability in the long run. |
| Fixed bug in scrollbar jump |
| Add planets (maybe)
| Add star names
| Add the option for other coordinate systems (Alt-Az, galactic)
| Add non-stellar objects
| Speed up the whole applet
| Allow fields of view greater than 120 degrees (i.e. use other
projections)
| Add a horizon, date, time and latitude (goes with Alt-Az mode)
| Add celestial "landmarks" like zenith or north pole and perhaps
a grid
| |
| Off-screen double-buffering pixmap is the wrong size
| Bottom scrollbar overlaps the side one
| Controls are somewhat obscure
| Please email me about any other bugs you find at
dolan@astro.wisc.edu.
