So if the manual says "turn off SR when on tripod" without specifying "only for long shutter speeds", when the camera itself turns off SR if you use a 2 or 12-second timer and when everyone else seems to suggest PEBKAC is the likely source of unsharpness, you response is "it has nothing to do with SR"? Why ask a question you seem to already have made up your mind about? Get the damned thing serviced by a professional if you're not willing to deal with suggestions provided. What is it you are after?

If you want to emulate the Nikon's look, you need to either shoot jpegs, use shadow correction, probably use bright setting, and bump saturation and sharpening a bit or create a Lightroom preset that does those sorts of things. These images look like they are a bit underexposed (not a problem if you are shooting RAW and trying to protect the highlights) and need some sharpening.
I wouldn't say that the D3300 images look great -- the colors look off to me and a bit oversaturated -- but it still shouldn't be too hard to get something you like with minimal effort.

The K-7 did have poor head room, but the Kx, K5 II, and K3 mentioned in this thread don't have that issue. They use much better Sony sensors.

What are you pointing at polaris? It should be the axis of rotation of your tracker, and it should be highly inclined (tilted upward) at latitude 62.5 (in fact, 90-62.5 = 27.5 degrees away from vertical).
Imagine you were at the north pole itself. In that case, the rotation axis of the earth points straight up (the projection of the pole onto the sky).
Where your camera points depends on what celestial object you are trying to track. If you can attach a ball head to your tracker arm, you can aim at will.
Conversely, I was never impressed with my efforts (and I'm a reasonably good DIYer, and a professional astronomer, to boot) at making a useful barn door tracker.
If you can afford a real astrotracker, you will be much happier!
You may find it better to attach your ball head to the "side" of the tracker arm, rather than the usual idea of putting it on the "top" - then the the tip/tilt of your camera will be rotated 90 degrees and may not seem so perilous.
