Based on the criteria you listed, the ST-9 is the camera that would most closely match your requirements:

* Shortest exposure times (because of bigger pixels.) You probably wouldn't use the reducer if you get the ST-9.

* Larger pixels are a better match for long focal lengths.

* Using the reducer with the smaller-pixel cameras will help, but not as much as the larger pixels will.

The downside of the ST-9 is the small overall image size (512x512).

If you use a reducer and can get really good guiding, the small-pixel cameras could be useful. But you will be working harder to achieve results, and if that is enjoyable to you, look more closely at the small pixel cameras.

Not quite freeware, but much less costly than PHotoshop are Paint Shop Pro and Picture Window Pro. They are more or less Photoshop clones. Also look into Mike Unsold's ImagesPlus; that was written with astro image processing in mind.

Double Images

Perfectly balanced isn't what you want. If the mount is perfectly balanced, it get to be _too_ easy to move it around, and it won't track/guide as well as it should. The mount should be a little heavier to the easy side (yes, this means adjusting weight if you cross the meridian) to keep the gears tightly meshed. Not a lot; just a little.

Also, if you are simply unable to take unguided images of more than a minute, that is to be expected with an LX200; it needs guiding, preferrably with an AO-7.

Pleiades LRGB wide field

Forgot to post the link to the full-size version. I actually created two full-size versions. One is the same as the one at the start of this thread, only original size:

and the other has different histogram adjustments, showing more faint detail:

I am curious to know which version you prefer. For convenience, I have included the small version of the faint-revealing image here.
