1.  The horizon line is too crisp.  This is especially noticeable
whenever I try to do a "night sky".  How do I fix this?

I use a "fog" object to make the transition from the ground plane to the
background smoother.  For day scenes, I generally use a very light blue
color (like <0.7,0.9,1>).  For night scenes, you could use a dark blue
<0,0,0.4> or black <0,0,0>.  See the POV-Ray documentation for a complete
description of the syntax.  Then play with the distance number until you
have a result you like.  You can also change "rgb" to "rgbt" or "rgbf" and
add a transparency value to your fog's color.  (eg, rgbf <0.7,0.9,1,0.5>
will always let half or more of the colors behind the fog through, (IIRC)).

2.  When I try to do a "twilight sky", i.e., dark _blue_,
with stars and clouds, it winds up being a *black* sky
(with stars and a few clouds).  How do I fix this?

What are you using to add clouds and stars?  I also noticed that your POV
file had a background color of <0.2,0.2,0.4>, which is a grayish dark blue.
<0,0,0.4> might work better.

  different idea for cockpit
 
(If you reply to this message, please follow-up to the appropriate, specific newsgroup. Thanks. :-) I came up with what I thought was an unusual orientation for a cockpit for a spaceship or mecha. I quickly built a set of mecha legs for it, and (...) (24 years ago, 12-Dec-00, to lugnet.cad.ray, lugnet.build.mecha, lugnet.space)
