I think that the FAQ included shipped with Celestia 1.6.0 should assume that version.

** Celestia 1.5.x is drawing planets and moons bright red. Why?
- In Workaround 2, no need to mention Celestia v.1.3.2 and 1.4.0 workaround


** I want to seeel all possible Celestia eye candy.
- Don't mention haze; this is a deprecated feature of Celestia. All the text devoted
to it keeps the answer from being as concise as it should be. The short and
appropriate answer is that any graphics card that supports OpenGL 2.0 will
show all the Celestia eye candy.

Something like this:
"Any graphics card with at least 128MB of memory and support for OpenGL 2.0 pixel
shaders will be able to show everything that Celestia is visually capable of.
Look for a graphics card that advertises either support for Direct3D shader model
2.0 or higher. Almost all graphics cards being sold today meet this requirement, 
albeit with varying degrees of performance. High-end NVIDIA and ATI cards will
provide the best experience in Celestia. NVIDIA's OpenGL drivers have tended to have
fewer bugs than ATI's."

Recommendations:
ATI Radeon HD series
GeForce 8xxx, 9xxx, and GTX 200 series

I think that might be all that we need to say to users looking to buy a new graphics
card. Most of the other hardware (e.g. Nvidia MX cards, ATI Rage) isn't even
being sold right now. Most of the current text for this FAQ item belongs in a
section titled something like, "How will Celestia perform on my system?"

We should eliminate the "Starting with Celestia v1.3.2"


** Sometimes when Celestia captures an image of its window, there's an ugly
bright rectangle in the picture.

Is this really still a problem?


** Celestia's galaxies are ugly, dim, grey blobs.

Eliminate "Since version 1.4.0 Celestia incorporates an improved rendering of
galaxies."


** Sometimes a screenshot captured in Celestia will have multipled boxes around
it, as if multiview was on.

I've never seen this--is it happening in recent versions of Celestia? If so, let's
group it with the other screenshot-related items in the FAQ.


** When I try to capture a picture or movie, the image is stretched out of
proportion.

This sounds like a bug with anti-aliasing with older cards/drivers. I don't know
that we should remove this item from the FAQ, but it would be helpful to mention
that this problem is more likely to appear with older cards.


** My planet's rings are drawn as featureless oval.

This should be completely rewritten. I'd suggest this:

"You need to use a smaller ring image, one that is no wider than the maximum
texture size supported by your graphics card. To find out what this size is, use
the "OpenGL Info" option in Celestia's help menu. For most graphics cards, the
texture size limit is at least 2048."


** Satellites orbiting the Earth are drawn extremely bright with no shading.

This item seems obsolete and should be removed.


** Celestia still crashes, draws funny stuff, or is extremely slow.

I'd prefer that people report bugs on the SourceForge tracker:
http://sourceforge.net/tracker2/?group_id=21302&atid=121302
The bugs forum should be mentioned as well, and we should provide the URL for
it in the FAQ item.


** Why does Celestia always use 100% of the CPU?

We should mention that on Windows, Celestia will not use much CPU time when it is
minimized.


** How can I make Celestia use less CPU time?

 It would also be useful to note that vsync should be enabled in the
Windows control panel (this is the default setting.) If vsync is not enabled,
Celestia will render frames as fast as it can, even if this is faster than the rate
at which the monitor can display them.


** I can't turn off the Red/Green diamond in the center of the selected planets.

This item is obsolete for 1.6.0. The new version of Celestia has an animated cursor
for the selection. Unlike the puzzling diamond, it will hopefully be immediately
clear to the user what the animated cursor is for. Currently, it is enabled/disabled
along with markers with Ctrl+K, but this might change before the final release.


** Sometimes the planets and moons are far away from where their orbits are drawn.

Eliminate "Starting with Celestia v1.3.2"

(I intend to address this problem in 1.7.0, but no need to mention that in the
FAQ :) )
