Lens flare added with GIMP. Temporary addition until I figure out how to do that
in Pov. And maybe I'll add some more stuff.

Have you seen Chris Colefax's Lens Effects (LNSEFCTS.INC) or Nathan Kopp's
NKFlare.inc?

I get severe rendering artifacts with those. Oh well, GIMP's lens flare is good
enough for now.

they're not perfect indeed.. I tried to improve on those; results can be
seen in my Babylon-video (link to youtube on p.b.animations) where I
used it quite a lot, but unfortunately I haven't got around to releasing
the sourcecode for that lensflare-system.
the problem isn't the code itself, I think it works almost perfectly..
the problem is the documentation, or rather: the lack of documentation
:/ I just can't seem to make the time to write some..

Well, this is what I get. It worked back when I was using 3.1g. Maybe the light
source is too far away?

light distance shouldn't matter AFAIK, in all honesty, I think you're
just doing something wrong :)
I'll see if I can write some basic documentation for my lensflaresystem
later today.

Maybe it needs replacement of ambient by emission?

I tried using it recently and apparently the colors are now messed up
due to the new gamma system. Not easy to fix, since they use partially
opaque textures, and since the gamma fix outlined on the wiki doesn't
take opacity into account.

I set
#declare effect_always_on_top=0;
and get the following (the prior image is with effect_always_on_top = 1).
However, now the lens flare goes behind the planet. So, now it's render errors
or having the effect end up behind objects.

Ok, it's not really perfectly documented, but at least it should be
clear how to use it now :)
see povray.binaries.scene-files :

I hope it's usefull to you!
