Yes, that's quite logical... I tried it, and it at least yielded roughly 
the result I want to achieve in the long run! Thank you for the tip... 
perhaps I'll up the extinction value to, let's say, 0.1 or 0.15, as the 
unlit side is of course somewhat darker than the lit side, irrespective 
of light filtering through...

...but I also found out, that with an exactly reciprocal scattering 
strength, the rings become too faint - so I instead made it ten times 
stronger (i. e. 1/3680 rather than 1/36800) - see attached images (first 
image: unlit side, second image: lit side)!

But, to bring my problem to a "meta level": although I now work more or 
less frequently since early 1996 with POV-Ray, I never got much beyond 
beginners' skills - since 2000 I keep track of this group, and I've seen 
thousands of incredibly sophisticated works (@Jaime Vives Piqueres: for 
example your autobahn scene!), and when I compare them to my puny 
primitive scenes, I'm close to cry for an euthanasia injection, as I'm 
obviously virtually unable to learn from my mistakes... and I HATE 
myself for being so dysfunctional!

And I'm really not sure whether having more hobbies than just POV-Ray 
(i. e. astronomy, electronic music, Afghanistan...) is the reason... to 
me it appears that not so few people who regularly contribute pictures 
here have access to, hmmm, time-compressing drugs which allow them to 
learn and work 72 hours a day...

See you in Khyberspace!
