Re: [APML] Veil Nebula in new HOT color space

["bert katzung" <katzung1@home.com>]

Hi Mike:
Very interesting concept! I have trouble with the mouse-over comparison,
however---with the mouse on it, the image breaks up into several horizontal
panels but I don't see any change in color, star size, or anything else.
Anybody else having trouble? May be my display adapter, I suppose...
