Sorry Fran, Work has been really crazy. Building a portable gas manifold, and diesel filter loop, installing a TGA, doing my regular barrier coatings plus got three lithium battery compositions that had to have zeta potentials run. Then I was told I have to go to NTRC and come up with a rig to duplicate the landfill gas engine.

Here's the image from the Sun & Moon portion of the skylab.

#1 click to turn on the moon texture.

#2 Press edit to bring up a texture window and change the moon image.

#3 Fiddle, Fiddle, Fiddle. This tracball controls the position of the sun and moon (badly). When the sun is on the camera half of the sky a yellow ball appears on the upper left. When the moon is on that half of the sky the blue crescent appears as shown.

#4 Azimuth Altitude. Click on the text and a box appears you can type into. It's much easier to make precise moves this way. Zero altitude puts the sun and moon on the horizon. The sun and moon are always 180 degrees apart in Bryce. Azimuth rotates the ball North, West, South, East.

It would be nice if every sun East was O and West was 180 degrees but pick any sky and It will be different.
